Pinup / Thumbtack


We use tack to paste notes or important sheets.
As you ca see this tack is conveniently struck a note.
But hands hurt easily because of the sharp pin.
And get hurt when tread tack on the floor drops out.

Normally tack has sharp pin so easy to get hurt.
We make a cover of sharp pin and change the form to tongs.
when you use this tack, just pick it up then it may fold.

Tack pin usally stabbed your finger. So, we put the cover on the tack pin. When not in use, put a cover over the tack pin. If you fold a tack like tongs, can show pin. You can use the tack do not hurt your finger.
