Hosco Japan center strip modified sanding block, two trapezium shapes

This is one of the most unique and particular parts of the guitar-making process. This is a unique tool conceived by a Japanese guitar builder. We reviewed the design with him to make it easier to use. Since there are two shapes and two types in one block, we've developed two versions, The MSB-1 and MSB2. It's to be used with self-adhesive sanding paper. Size : 107 x 30 x 28mm
