These whimsical, art glass toadstools are shaped from 2000-degree hot glass coated in our glow-in-the-dark pigment. Any lamp or sunlight will charge the color causing a soft glow when placed in a dark setting. A great bedside night light! The tall toadstool is approx. 3 1/2 inches. Aren't they cute paired together? Expect variations in accent color and shape, as these are handmade one at a time by our glassblowers.
