A diz is used for combing top to prepare fiber for spinning worsted yarn. This bamboo diz is laser cut with three precise hole sizes to pull your fiber through: 1.5mm, 3mm and 5mm. It is 2" x 3" and cut from 1/8" bamboo. Each piece is hand sanded after laser cutting to smooth out corners and edges. Because it is made of a natural material, the appearance of each needle gauge may slightly vary.
