L tape measure / tape measure

L tape measure

More protections to your hands come from L tape measure.

While the traditional tape measure is rolled back at high speed, the instability of restoration process may create unavoidable harm. How to use tape measure safely and effectively has led to a long-lasting problem.

L tape measure here is designed to solve this problem. When the 90° folded baffle on the tape measure opens out, it can effectively reduce the instability of restoration. And a rubber sheet on the baffle helps to buffer the high speed of restoration. The convex shape of the bottom of tape measure prevents damage to your hands.
