While using a tapeline, we will meet various of problems. For example, users have to holding the tapeline while using a pencil to mark the length on an object. Besides, the shell of tapeline will also affect the accuracy of measurement. To solve these problems, “Tapeline Writer” set a charcoal crayon at the head of the ruler to help measure the length.Its shell is printed with scale so you can add the length of the shell to the length of the ruler to measure some special length. And the shell has a 10° chamfer so that it can be easily taken.
