6 Upper Deck Marvel Vibranium AP. Email for character permission (I have a list of characters I an not allowed to draw on these). Please note this is a very, VERY slippery surface that needs special treatment to preserve the drawing. Imagine a dry-erase board. The only medium that sticks to these is Sharpie and gel pens. 30$ each plus shipping (these are more work than normal cardstock) Limited!
