10 Pack 12″ x 26″ Brodart Just-A-Fold III Archival Book Covers – Adjustable, Clear Mylar

I have been using these to protect my Stephen King first editions/first printings and they are wonderful. So easy to use. I’d say the hardest thing is making sure you have the top of the dust jacket all the way to the edge of the joint of the mylar sleeve, that way no white paper is seen at the top of your dust jacket. Once you have it snug into that joint, try to anchor it down with something heavy, so you can go ahead and fold the bottom portion. A bone folder is highly recommended for that.
