Card holder is designed to hold both a slabbed card (PSA, SGC, BGS) as well as a standard top loader. There is a small groove to keep the toploader at the same angle as the thicker slabbed card. I designed this because I didn't really like the typical "Easels" that you can buy and was looking for something that would have a little more polished look when on display. I printed this with a metallic copper PLA.
