Using this 2.5 - inch flashing crystal putty is super easy. Just give it a gentle squeeze or a light tap, and it will start flashing, which is really fun to watch. When you're done playing, keep it in a cool and dry place. Avoid exposing it to extreme heat or moisture as it might damage the non - replaceable batteries.
