Using this World's Smallest Glow Worm is super easy. Just give it a gentle squeeze, and its head will light up to create a soft glow. It's great for kids to hold at bedtime. When it comes to maintenance, make sure to keep it away from water as it has a battery - powered device inside. If the glow gets dim, you may need to replace the batteries. Always handle it gently to avoid any damage to the stuffed body or the lighting mechanism.
