300pcs Glow In The Dark Garden Pebbles Stones for Walkway Yard Graved Fish Tank Plant Pot Decoration (Mixed Colors)

• The glow stone could be used for aquarium tank, garden lawn, plant pots, driveway, swimming pool, pond, pathway and so on. • Glow lasts approximately 3-4 hours in the dark after direct sunlight or UV light exposure for 20 minutes. The glow will be faded out gradually. • The glow gravel is made of polystyrene and phosphor, non-toxic and non- radioactive. Each package of glow gravel contains 100 medium-sized pebbles, which is sufficient to evenly cover a small fish tank. • Just spread evenly on the bottom of the fish tank or the garden pathway surface. You can make them into the shape you like (e.g. heart, star). For better visual effects, please do not stack stones on top of each other.
