I use Pro Support Perfect Fit for my Topps baseball cards. These will not wrinkle over time in a 9 page sheet binder like standard penny sleeves. Usually Perfect Fit sleeves are meant for Game cards like Pokemon-size, so most Perfect Fit sleeves are rather too small for the larger Topps Cards, but the Pro Support brand appears to fit just right. Although not as thick as Vault X Support Fit, the Vault X are too small for Topps size cards. Also know there are slight differences in card width within Topps various sets and thicker cards like refractors tend to bend if not kept rigid in snap-tite cases like Pro Mold P1-ii This product also has inconsistencies as some are SLIGHTLY smaller than the majority of the protectors you get. But you get plenty wo there is value also.
