The Crawler Crib offers an easy soak-and-go solution for keeping worms cool and lively. Simply soak the fiberboard container in water until saturated, and then add bedding and worms. The water's evaporation acts like a swamp cooler to keep bedding and bait cool all day. Empty the cabin, let dry, and you're ready for the next trip. Double-locking single door with corrosion-resistant molded edges for easy access. Dimensions: 8" x 6" x 7".
