Add sparkle to playtime with Toysmith Light Up Gems. Each gem is made of silicone, great for squeezing, and fits in the palm of an adult hand. Hit the flat side of the gem against a solid surface to activate the light inside. Light will flash for a total of 20 seconds each time it’s activated. The light will start out slowly, flashing once per second, and then speed up before it goes out. Gems are available in blue, purple, and red.
