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! Our toadstools stand 3-4 inches tall. Expect variations in accent color and shape, as these are handmade one at a time by our glassblowers.
