How to collect blind boxes without overspending: a budget plan, the maths and the return rules

A word on scope. We are not financial advisers or therapists, the prices below move, and the odds on any real series are set by the brand, so treat our maths as illustrations and read your own box. If your spending already feels out of your control or is causing you distress, talking to a professional you trust is a better step than any budgeting trick.

What a box actually costs: price points and the sunk-cost trap

Prices differ by series, size and country, so check the product page before you plan. For reference, a deal listing on Slickdeals showed Pop Mart's official Amazon store selling a Labubu Big into Energy blind box at $27.99, and the Open magazine analysis of Pop Mart's US site cites the same series at $26.99. Take the high end of that range for planning: the cost of a "case" or set is the box price multiplied by the number of boxes, with no volume discount to count on.

The expensive part is psychological rather than arithmetic. A Malaysian psychologist quoted in The Star describes the sunk-cost effect: after buying many boxes, people feel they have invested too much to stop. She adds that the behaviour becomes a concern when buyers feel guilty but keep buying. She also cites a study, which we could not trace, saying nearly half of blind box buyers kept buying despite being unhappy with duplicates; treat that figure as unverified.

A separate, brand-commissioned survey is more useful as a warning than as evidence: in 2019 Pop Mart asked Frost & Sullivan to survey more than 1,000 consumers, and reportedly around 70 percent of pop toy consumers would buy blind boxes three or more times to get a specific design. That is a sales-side finding, and it describes how normal repeated buying is.

Reporting on collectors makes the same point with names attached. A feature published by the Taipei Times, and carried by AOL, quotes a researcher who has studied blind boxes and found that most US consumers first meet them in stores and buy impulsively, and the story features adults who spent up to $270 in a single week or about $400 in a month and felt out of control. These are anecdotes and a small research sample, not population statistics, but the mechanism they describe is easy to recognise.

The maths of chasing a full set

Suppose a series has r regular designs, each equally likely in every box you open, and you buy boxes one at a time. The expected number of boxes needed to see every design is r times the sum of 1/1 through 1/r — a classic result known as the coupon-collector problem. These calculations assume equal likelihood and independent boxes, which real production may not match, so use them as a rough guide only.

Read the table as a price tag on random completion. In a 12-design series, 12 random boxes give on average only about 7.8 different designs; the other four or so are duplicates. Buying a "full set" the random way is not buying 12 figures for 12 boxes, and the last few designs cost the most, because each new box has a shrinking chance of being a design you lack.

Our pull-rate guide works the same arithmetic per series, and the Labubu section covers what the odds look like on the line most people start with.

Secret figures

Brands print or state odds for the rarest figure in the series, and they differ from series to series. Pop Mart's Canadian shopping policy says rates are set per series and shown on the product page or packaging, so read yours instead of trusting a forum number.

If a secret figure appears at 1 in r per box, the chance of getting at least one in n boxes is one minus (1 minus 1/r) raised to the power n. At 1 in 72 that is about 8 percent after 6 boxes, 15.5 percent after 12 and 28.5 percent after 24. At 1 in 144 it is about 4, 8 and 15 percent. The lesson is that 24 boxes bought "to get the secret" still leave most people empty-handed.

Pop Mart's Australian terms add that a secret figure replaces one standard figure and that it does not guarantee a secret in any purchase. The practical rule is to buy a series because you like the regular designs, and to count a secret as a bonus rather than a plan.

What the return rules do and do not protect

Return policies differ by region, so check the one that applies to your store, but the pattern is consistent in the policies we read. Pop Mart Australia says it does not offer refunds or exchanges for a change of mind, and its return page lists not getting the expected item from a blind box as a reason it will not accept returns. Pop Mart Canada's FAQ says that because of the nature of blind boxes it does not accept returns for personal reasons, and that an opened box is considered consumed. Third-party sellers such as Mentastore say the same for Pop Mart blind boxes.

There is a narrow remedy for real faults. Australia's terms say that a customer with a major quality problem may get a replacement or refund at Pop Mart's discretion, and its page advises opening in the store after the receipt is processed and recording the unboxing on video, no later than two days after purchase. The Australian terms also say that if a whole box contains a duplicate, the missing regular figure will be provided and the duplicate taken back, and that a card that does not match its figure will be corrected. That whole-box rule is in the Australian terms; do not assume it applies in your country without checking.

One more rule saves money. Pop Mart Australia tells customers not to weigh or pinch boxes, and says a customer who damages a box may be liable for its full price. Whatever the local rule, "feeling for the secret" is not a strategy the brand supports.

Singles, cases, resale: comparing the three ways to buy

Before buying a specific figure second-hand, look at what similar figures actually sold for. The Open magazine piece found that on StockX a box from Big into Energy averaged $6 across 36 sales in the preceding three months, against a $26.99 retail listing, while the series's identified secret averaged $70 across 95 sales. The first number is a reminder that a common figure can sell for far less than the box price.

Do not budget around resale gains

Resale hopes are the most common reason people overspend. Reuters-syndicated reporting says resale prices worldwide fell after their summer 2025 peak, and one data point from the Chinese platform Qiandao shows a Labubu design that launched in April 2025 peaking above 500 yuan in June and falling to about 108 yuan. Reports in December 2025 said items that once sold for double or triple retail often traded below it, with a Bloomberg-sourced article citing comparisons to the 1990s Beanie Babies boom.

More recently, CNBC reported on 28 October 2026 that Pop Mart's third-quarter revenue fell 45 to 50 percent, with the Americas down 70 to 75 percent, and Inside Retail Asia reported on 30 October 2026 that resale prices had fallen by more than half. Pop Mart itself has said falling resale prices reflect supply rather than demand, comparing the situation to concert tickets, so reasonable people read the same data differently.

You do not need to settle that argument. A blind box is a consumer product, and the sensible assumption is that its resale value is a bonus that may not arrive. A journalist at Galaxus put it more bluntly: once a figure is a mass-produced product, it has little chance of appreciating. If a purchase only makes sense when you imagine reselling it, it does not make sense yet.

A ten-minute budget system

1. Write the goal. Decide what you are collecting: one character, one series, a full regular set, or simply the fun of opening. Each goal has a different cost.
2. Set a monthly cap you can afford to lose. Pick a number you can lose without changing your month, and use cash or a debit card. The Star's psychologist links credit card access with harder-to-control spending among young people.
3. Convert it to boxes. Divide the cap by the box price to see how many boxes you get. At $27.99 a $100 cap buys 3 boxes and a $200 cap buys 7. If the answer is far below the number the table says you need, switch goals — for example to a sealed case, or to buying the specific design you want.
4. Add a cooling-off rule. Wait 48 hours before any purchase that is not in this month's plan. Release hype is designed to make waiting feel costly.
5. Keep a simple log. Write down what you bought, the price and what you got. Nothing changes behaviour like seeing the total.
6. Stop at the cap. Stop for the month once you reach the cap, even in the middle of a series. Spending to recover earlier spending is the sunk-cost effect at work.
7. Handle duplicates later. Swap or sell duplicates only after the month ends, and do not count the proceeds toward next month's cap until they arrive.
