Crystal Clear Bags traditionally come with a top flap with a re-sealable adhesive strip allowing it to be folded and sealed over the bag's opening. It's as easy as inserting an item, peeling the adhesive cover strip, and then folding and pressing the flap to the bag to seal it.
The flap seal allows for items to be smaller than the height of the bag as the flap seal can be folded past the opening of the bag if needed.
