Large size Reptile utility hide boxes sized 13.125"x 9"x 3" tall.
These are designed to fit in most major brand 28-41qt tubs and are well suited to the Iris CB-70 tub. Good for average size adult ball pythons, medium boas and Woma pythons.
Remember, you want to select a hide that will be a snug fit for your reptile. If it is too big it will not offer the security they need!
