The samples I posted are from Derun Leather (Dongyang Derun Leather Co.). They really do appear to be a major player in the industry. Heck, they even have a Facebook page: www.facebook.com/glitterleather
If you add phrases like glitter PU
, glitter leather
, or glitter synthetic leather
to your search, a few more names come up, but a lot of the products look like they come from Derun. Maybe you can find a distributor willing to sell in smaller quantities. Good luck!
