Many designers used to complain that it is hard to measuring the irregular, soft objects using traditional rulers. To solve the problem, the back part of a measuring tape was made sticky. The tape could stick to any surface with curves and angels, which cannot be achieved by traditional rulers. Additionally, the sticky measuring tape could be cut off and sticky on arm or other human body parts. With the help of the measuring tape, a designer could use their body as measuring tools. Hence the whole measuring process could be done easily with one hand.
