Hello any and all. Many years ago, I bought 100 of the (see attached) sleeve. It's not matte, which I prefer, but the design was just so awesome. The sleeve is curved a little bit, so you can't make the small little dragons in the upper part of the skulls flames, but they are there.
I have not been able to find those sleeves since. And obviously searching "dragon sleeve flame" is super generic and yields many results, but none that I can tie back to the sleeve that I want. I don't remember who made them.
