NeeDoh’s “squish-mas” advent calendars, priced at £30, sell out in official UK stores after going on sale earlier in the year. The set includes 24 mini stress-reliever toys.

Retail availability appears to follow a similar timeline across outlets, with the calendars first released in July and a second release date in August. Sources link the product’s popularity to the wider NeeDoh craze, describing the mini toys as versions of the viral, ASMR-style stress relief items.

Both outlets also note that the sold-out status is contributing to resale pricing on secondary marketplaces. In particular, at least one outlet reports that calendars are being listed for roughly double the original price on Vinted, reflecting increased demand after official stock runs out. The coverage focuses on consumer uptake and the shift from retail purchase to resale rather than changes to the product itself.
