These sharp glass head pins by the Japanese brand Clover are particularly suitable for patchwork and quilting. The heat-resistant head is so small that it can be easily stitched over with the sewing machine, while still remaining visible. These quilting pins are especially handy to pin together several patchwork blocks for a quilt. They are 36mm long and have a diameter of 0.50mm. One resealable case contains 50 patchwork pins. Supplied per 1 pack.
