In the dark, they can glow naturally for 30 minutes to 2 hours. If the brightness is insufficient, they can be exposed to light again. The product can repeatedly absorb light. Quantity: Each order contains 300 luminescent stones, weighing 120 grams. Applications: Suitable for DIY decorative vases, aquariums, aquarium ornaments, gardening, swimming pools, ponds, bar decorations, home, parks, bird fountains, water features, landscaping, flower pots, potted plants, patios, lawns, garden aquariums, and craft decorations. Safe and Non-Toxic: These shiny luminescent stones are made of synthetic resin, are non-toxic and harmless, contain no radioactive substances, and are safe for humans and animals. The luminescent stones are harmless to the human body. Beautiful Appearance: The luminescent stones are rhomboid in shape with a smooth surface.
