Scottie B youtube channel
I was looking for tips on improving my pictures of cards for auctions and came across Scottie B. I imagine he's old news for some and wanted to share for those who haven't heard of him.
Here is a link to a PSA slab test where he shows lack of UV protection and strength of the holder. He has a lot of content that I haven't sifted through yet. https://youtu.be/SrYTA3PU7MM
