TSV Glow-in-the-dark garden pebbles are crafted from safe and durable resin. They utilize a sustainable luminous principle, absorbing and storing light energy during the day to radiate a captivating glow for 5-6 hours at night. Recharge them with light if needed, as their brightness peaks in the first hour and gradually fades. Maximizing exposure to sunlight ensures optimal performance. These luminous stones add a decorative touch to vases, fish tanks, crafts, and outdoor spaces like gardens, patios, and lawns.
