Scrach-free / Thumbtack

Scrach-free

Sratch-free thumbtack is tool resembling a flower pot.People often get upset when scratched by a thumbtack. Scratch-free thumbtack is made to counter this problem.
Compared to traditional thumbtack,the sharp nail is wraped by a rubber spring,which makes it like a flower pot.
When utilizing,just put it on a plane and press it into it.
You dont even have to worry about how much forces you can bear on your fingertip because the place you are pressing is secured by a leaf-shape tail.
