These large non-toxic black water gel beads are great for floating candles and floral displays. Each order comes with 100 grams of beads. The original size of the beads is 1/8', and they expand to 3/8' after absorbing water. There are around 2000 - 2500 jelly fillers in each order, and they can fill a 28oz container after expansion. To use, put one pack of beads in about 1.5 quarts of water (distilled water is best) and let them expand for 6 - 8 hours. Then, take the expanded beads out and pour them into vases or bowls. Remember, these beads are for decoration only, not a toy for kids. Keep them out of reach of children and don't consume them as they may pose a choking hazard.
