This is a stone that has been processed with a measuring tape embedded inside. I received it about 30 years ago and have kept it in a drawer at work. Please consider it more as a design item than a practical tool. As a measuring tape, it might be a bit heavy. Of course, it can be used. Dimensions: Body - 72 x 67 x 42 mm Box - 105 x 82 x 47 mm Weight: 230g, Measuring tape length: 2m (Made in Japan) The box has aged over time, so please understand. The body has also slightly changed in color and luster, but since it's stone, it's not that noticeable and has developed a deeper character.
