I'll admit that objects you buy from Temu are often 2-3x larger or (more likely) smaller than than you expect them to be, but often they are OK. Having worked a bit in recommendation engineering I have a lot of respect for what they do.
I've built a number of nice puzzle kits with Chinese themes I bought from Temu but don't actually use any of my kemonomimi supplies I bought from Temu and instead rely on American fashion brands, Etsy or commissions.
