Frequently Asked Questions

What is a perfect-fit sleeve for?

It is the snug inner layer in double-sleeving — your card goes in here first, then into an outer play sleeve.

Do they fit One Piece cards?

They are a very snug fit and work best for Pokémon and standard cards. For thicker One Piece or alt-art cards the fit can be tight — if you want an easier fit there, choose our Soft Sleeves.

Can I use these for grading prep?

Yes — ultra-clear, clean protection that is ideal before sending cards to PSA or CGC.

Which outer sleeves pair best?

Our Swift and Blade play sleeves are sized to go over a Perfect Size inner sleeve.
