What our readings say: 4 of 7 reading-days recorded. We judge a seller's discount only after 7 separate days of our own readings.

AliExpress prices this listing at 81.50 CNY. The $12.29 above is that figure converted by their affiliate API. AliExpress’s own site converts at a slightly different rate, so it may show a few percent less — the CNY number is the one neither of us converted.

The price on AliExpress may have moved since our latest reading, 6 Nov. Purchase happens on AliExpress, under their terms — we never handle payment, and we earn a commission at no extra cost to you.

Seller lists it at $30.60 — a claimed saving of $18.31. AliExpress does not verify that figure, and 13.2% of the listings we track make a claim in the same 60-69% range, so on its own it means very little.

Comparable products we track

8 products in Toys & Hobbies close enough to compare on price — 6 are cheaper than this one.

How this compares to everything else we track

We show 10,796 products, one per title, in Toys & Hobbies. At $12.29, it sits above the middle of that category, which is $6.99 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 60% off. Only 19,131 of the products we track claim a discount that large — 13.2% of the catalogue sits in the 60-69% band, so this one stands out. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

AliExpress reports 252 orders for it. For comparison, the median listing we track in Toys & Hobbies reports 97 — though a category holds very different kinds of thing, so read that as scale rather than as a ranking. Order counts come from AliExpress and are not a claim about price.

We have recorded this product’s price on 4 separate days since 2026-11-03, and it has moved 2 times in that window. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.

2 shops we track list this same product, between $12.29 and $12.45. Same title, same photos, different seller — AliExpress does not group them, so the price you see depends on which listing you happened to open.

If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
