Product Review

This chalk line is made by Shinwa Measuring Instruments. The line/string is much finer than other chalk lines producing a more precise line (line is just 0.020" thick) . The line/string passes through felt blocks for a more even distribution of chalk. The line/string is wound via a folding hand crank. Chalk can be added by opening the hinged door. Comes with 2 different attachments: 1) a metal hook for fitting over a nail or hanging over an edge or 2) a metal pin. Line/string can be easily replaced by opening up case. Line/string is 15 meters or 50 feet in length.
