You are buying 20 feet of 3" wide water activated kraft paper tape for vintage box repair. New from bulk roll (No box). Just cut to desired size with scissors or a utility knife, moisten with damp sponge and apply. This is what Lionel trains used on the ends of corrugated engine boxes in the postwar era, Bachmann used tape like this on Plasticville box corners. Used to reattach box flaps, repair separated box corners, repair tears from the inside, reinforce box flaps that are close to separating. Shown with a repaired box flap for demonstration only and no box is included, just 20 feet of tape.
