Size 15/0 seed beads are the smallest seed beads we carry. Most jewelry makers use them for bead weaving and stitching projects, but they can also be used in crafting projects that require embroidery or embellishment. Each tiny bead measures about 1.5mm and has a hole size of 0.7mm. These Japanese glass beads are of the highest quality and are uniform in size and shape. You will get about 2500 beads per 10 gram package.
