Beautiful Hydrating Water Beads for Plants and Flowers. Decorative, Colorful and Eco Friendly Water Beads are a crystal polymer soil substitute for plants and flowers. The beads absorb over 100 times their weight in water to form glass-like pearls that slowly release water back into their environment. The brilliance of the beads makes them ideal for flower, plant and candle arrangements. Choose from an array of beautiful colors; mix them up to make your own beautiful and personalized arrangements. The beads are colorfast, eco-friendly and non-toxic. They are lighter and more attractive than stones or glass marbles. You can reuse your beads over and over, just dry them out and repackage them. Net Weight - 10 grams (.35 oz). Each bag makes about 4 ½ cups of beads. Beads are not to be flushed down drains, swallowed or frozen. Keep out of direct sunlight and keep out of reach of small children. They are safe, fun and easy to use. Detailed instructions are included with each order.
