Letter Tie.
Patent for a new and improved clasp for letters. This design calls for wire or sheet metal to be shaped into a suitable size and shape for letters, including tabs on the ends to snap together to fasten the letters. This eliminates the need for twine or string, which reduces the flammability of the packages.
