Felt gaskets for boxes, etc. I have seen them in Luftschutzapotheke and wood crates. These are often missing or moth eaten; this is your chance to replace a missing or damaged one with original parts. These are a civilian product, so they advertise use for windows, doors, cars, etc. Price is for one. The paper wrapping is discolored and they do show storage wear. They measure 5/8" wide and the packaging states they are 3 meters long.
