It's as simple as that! Our product has been specially designed for you to easily measure any part of the body. It's so simple you wonder how you ever got by without it Effective Just press a button and the soft vinyl tape hugs your body and gives you an accurate measurement. Measuring biceps, forearm, thigh or calf becomes child's play You're covered! They can measure up to 150 centimeters or 60 inches. The tape is marked in centimeters on one side and inches on the other side Easy to carry Our product is stronger and more durable than others. It costs a bit more, but it pays off in the long run The case is included in the measurement. To simplify the calculation, we imagine that the circumference of the arm is 38.1 cm. If the tape measure started at 0, the measurement would be approximately 33.02 cm (13 inches) since the intestinal part measures approximately 5.08 cm (2 inches).
