Review on ClearBags Seal Top Closure Bags, Perfect Fit For 4X6 Photos, Art Prints, Pictures, Posters Resealable Adhesive On Bag, Not Flap Crystal Clear, Archival Safe Pack Of 25 (4" X 6") by David Ocampo

The best part of these protective cover bags is that you can easily remove the artwork without the risk on ruining the surface of the work on the adhesive strip. I have had other bags where the adhesive is on the top flap and when you removed the work they could become stuck on the adhesive. These bags eliminate that problem by having the adhesive on the back outside part of the bag where the artwork cannot come into contact with the sticky adhesive strip. Brilliant!
