It is often very difficult to dismantle fixed nails in our daily life. The dismantled nails will left damages on the body surface even if they can be dismantled. The new type nail we designed has a groove on its surface. The nail can be pulled out easily via the added groove and it will not left any damages. Meanwhile, the new design will not increase too much costing and processing difficulty. Our design philosophy is to transform "impossible" into "possible".
