The Firefly glows brighter than its natural namesake. It can be used as a key ring gadget and can also be attached to zips or other things you would like to be able to find in the dark such as pets, first aid kits, tent entries or torches. The stick continues to glow for 10 hours and maintains its luminescent properties for 10 years. The container is made of ABS plastic and is highly durable, and the luminescent granulate is non-poisonous and environmentally friendly.
