Lee's Pet Products - Kricket Keeper LargeCrickets provide valuable protein, vitamins and minerals for your pet. In the past they have been difficult to keep for any length of time, but now, with Lee's Kricket Keeper, hobbyists can maintain up to 30 medium-sized crickets for a week or longer. Because crickets love hiding in dark confined places, Lee's has provided two texturized, black cylinders that perform as combination refuge/feeder tubes.Large - UPC: 10838200787
