Ben & Bel Glow In The Dark Glass Marbles, a Set of 20 Pcs Multi-Color Dotted Marbles for Marble Run Game, DIY and Home Decoration

Rich in Colour: Our 20-piece glow-in-the-dark glass marbles contain as many as 8 to 10 different colours, which is quite rare on the market (most other products are limited to just 4 or 5 colours). Simple to Power Up: We've made our marbles safer for kids by removing the need for UV light charging. Just bring them close to any light source, like a lamp, torch, or sunlight, when they need a boost, and watch them glow bright! High Quality: All the marbles are handmade from high-grade glass, and are strong, smooth and glossy. Their fluorescent material is well sealed within the glass. Indoor & Outdoor Toy: These shiny and unique marbles are very suitable for, but by no means limited to, use in marble run games. They shine brightly as they zig-zag down the marble run, adding extra fun when playing such games. Multi-Purpose Use: Playing with our marbles can relieve stress and anxiety, and they can also be used as decorations in the home, including in aquariums. Why not use them as a reward to encourage children's good behaviour., Manufacturer: Ben & Bel
