Cleverly radians / Thumbtack

Cleverly radians
Cleverly radians

In everyday life, whether it is in the learning, or in the process of working with a thumbtack, are faced with the same problem, thumbtacks bar into the wood or publicity column on bad pull.If good pull without completely headlong, not firmly fixed.So, I designed a pushpin edge upturned radians, so pull pushpin even more convenient, do not need us a lot of effort to pull pushpin.
