These glow-in-the-dark pebbles are crafted from natural resin, ensuring they are safe, non-toxic, odorless, and free from pollution. Finely polished to have smooth and rounded edges, they provide a secure using experience. They appear milky white during the day and can absorb sunlight or artificial light for over 4 hours, emitting a charming blue glow at night. A single pebble can glow for 1-2 hours, while gathering 10 or more pebbles together enhances the brightness and extends the glowing time to over 5 hours (when 100 or more pebbles are clustered, they can glow brightly for over 7 hours). They can be freely paved on garden paths, along the edges of flower beds, or used to decorate fish tanks, vases, swimming pools, water features, etc., easily creating a dreamy landscape. Whether for DIY creative gardening or embellishing indoor and outdoor spaces, they can be used immediately after simple light exposure, adding a romantic atmosphere to life. They are an ideal choice for courtyard decoration and aquarium landscaping.
