工具尺改良 / Improved tools ruler


description of design
When you use traditional tapes, your hands are too busy to make a mark. So we make a slot space in the bottom of the improved tape to put in a lead bar. All you need to do is just to touch the tape slightly after you got exact datathen you will get the mark which can make following measure convenient. As for the tapeline-shell, an ideal ergonomic design is adopted to make it more user-friendly. Since the lead bar wear out, we have a reserved room for lead bar storage in the rear of the tape shell.
