These glow-in-the-dark pebbles are crafted from durable resin and high-quality luminous materials, with finely polished smooth round surfaces measuring 5-8 mm in size. They come in 12 distinct shapes, which can be arranged together to create a varied and visually appealing decorative look. These versatile pebbles work for both indoor and outdoor spaces, with different quantity options to suit various needs: 200 pieces fit potted plants, succulents and micro fairy gardens, 500 pieces work well for small fish tanks, flower pots and vases, 1000 pieces are great for gardens, lawns and aquariums, while 3000 pieces make charming decorations for yards, patios, walkways and driveways. They absorb and store energy from sunlight or indoor lights, requiring at least one hour of exposure to achieve optimal glowing effect, then emit soft warm light for 3 to 6 hours in dark environments before gradually dimming. They are reusable, and simple care steps can help maintain their performance over repeated uses. Color: Blue.
