This patented tiny triangle shaped tool will be your new favorite jewelry finding!  Make necklaces, pins, earrings and more.  Simply attach the triangle to chain or other findings, insert the shank of any button into the opening in the center, secure with the cotter pin and wear your buttons!  No harm comes to the buttons and you can change the buttons any time you choose.
Two sizes are available: 5/8" and 1". The smaller adapter works well for most metal shank buttons, while the larger works best for chunky shanks such as Celluloid or Bakelite buttons.
