Great post. Fantastic examples via blowout and Amazon. I would give you gold if EFour was similar to Reddit.
These are actually the same sleeves that I have been noticing the most scratches from. But most perfect fit sleeves do the same damage if you slide them in with pressure on the front or back of the slab. Most people don’t even realize they do damage to the slab.
Even PSA puts sleeves on their higher tier returns without even realizing that they damage the slab. Thank you for validating my concerns.
