Glittering aurora acrylic beads, heart-shaped, mixed colors, 8 pieces per pack. Size: Approximately 18mm (length) x 22mm (width) x 15mm (thickness). The colors in the photos are examples, and the mixed colors cannot be specified. Please understand. The back is shaped to allow elastic to pass through, and 2mm elastic can easily be threaded. They sparkle and are cute when light hits them. Why not try making them with your children? I also have several other accessory parts for sale, so please take a look if you'd like. Thank you to anyone who is interested.
