I received this as a gift, and it's new and unopened. Ryoji Nakajima's simple line drawings of animals have been made into a pair of keychains. They use a retroreflective material (reflector) that reflects light back towards the source, so they shine when headlights hit them, alerting drivers to their presence. The animal parent and child are a set, so you can use them with someone special.
