PSA + CGC slab sleeves

I received these sleeves as part of a bundle and is perfect for both PSA and CGC slabs. I asked pennysleever if they would make CGC and they responded quickly insisting they are similar in size and by golly they work great. Thanks Pennysleever

Perfect sized mags

The pennysleever hit it out of the park with these mags. Perfect fit for cards. I have had ultra pro and BCW and my cards move around in those brands. You have a returning customer for good and also great addition with the new colored bordered mags!
