Pull back the lateral scale, starting from 5cm. This is a deliberate design, because after the ruler is inserted into the groove, the 5cm at the radian of the ruler body is removed in this design. The direct reading of the measurement results is accurate.
The inside scale starts at 1cm and can be used as a normal tape measure.
Let me first explain the question that the customer asked: how can the beginning of the measuring ruler be 5 centimeters short? All the waist measurement measures in the world are 5 centimeters short. Because the radian at the end of the tape measure has already been 5 centimeters, so it is designed to be 5 centimeters short.

Note:
1. Due to the reason of light and display, there may be a little color difference, please take the actual prevail.
2. As the size is measured manually, there will be some errors, please understand!
