Transform your mason jar into a glowing firefly habitat. Jarware's Firefly Kit is made of BPA free, recycled materials and fits regular mouth mason jars (jar not included). The kit comes complete with a mesh net for catching and a perforated lid. Snap, catch, glow. It's as easy as that. Nothings says summer like fireflies. Typically not seen west of Kansas, these beautiful glowing insects live in rural and suburban areas and are most likely to be found close to water like lakes, ponds, and puddles. Catch a jar full and watch them shine. Especially designed to bring even more uses to your collection of jars because, let's be honest, everything's better in a mason jar.
