A round glass seed bead approx 4mm in size, with approx 1.5mm internal hole. Approx 85 beads per 7.5gm bag. Japanese (Miyuki) seed beads are well known for being consistent in size, shape, and hole size. This makes them not only great for strung necklaces, bracelets, etc, but also  particularly good for stitched and woven projects.
