Description
Our 4 mil conservation quality polyester ("Mylar") envelopes are the best available plastic enclosures for comic books, and are used by both collectors and dealers to safely store their collections. Other clear comic book bags, including zip-lock bags or vinyl envelopes may release gasses which can harm your comics, turning them yellow and brittle. Our envelopes are welded on three sides and open on top. Available in packages of ten.
