if ya want a faux fur tail from amazon/temu/aliexpress or any other fast fashion place (i dont support em but some people cant afford etsy yk) then go for one with a belt rather than a keychain

tails with belt attachments are usually seen as a furry thing rather than being for alt people/therians but theyre generally less likely to be made from real fur

if ys think fur is real, cut off a small piece and burn it
if it melts its fake but if it singes then its real
