Wear to boxes. One roll of white tape has been used. Black tape may have some used, and box is torn on corner.

This is cloth tap for mending and binding books, music, maps, notebooks and catalogues. I don't know if the tape works any longer - this is purely for collectible purposes.
Each box had 9 yards originally. Two No. 5 are full, one is used. The No. 8 may have been used, but it appears close to full
Each box measures 2 1/8" x 2 1/8" x 1 7/8". The black tape box is lidded, the white boxes slide to open.
