Period German Zellglas Clear Tape
Period German zellglas cellophane tape - its basically scotch tape. The price is for one box containing 1 roll of tape.
You have two choices: Blue (20mm wide) or Brown (15mm wide). All are in good condition.
These are new old stock. I am not sure if the tape would still be any good. I did not test any since they are all still completely wrapped. Each box is roughly 1 7/8" square.
