These untreated glass beads are for filling and filling weighted blankets and other crafts. Not all glass beads are the same. Our glass beads are untreated, high quality, and consistently shaped. Others can be made from recycled glass such as sand or rough edges. These glass micro beads are perfectly round, smooth and move with ease. They are the perfect filler for various stuffing and filling projects, such as: weighted blanket, anxiety blanket, weighted quilt, weighted quilt, weighted vests, cross fit bags, medicine balls, rifle bags, gun rests, lives like dolls, reborn dolls, sensory toys and plush toys. These are high quality pure round glass beads that are washable and tumble dry. Made in the USA, these weighted beads are an ideal alternative to poly beads or plastic pellets. Because glass beads have a much higher density than poly plastic pellets, so they are less bulky while providing the same weight. For visual comparison, see photo in the list.
