100% natural nursing shells, from the bottom of the ocean and carefully polished, are nipple shields that soothe and reduce many ailments associated with breastfeeding (overheating, hypersensitivity, irritations, cracks, among others). Depending on the diameter of the flat nipple areola, around the beginning of the ninth month, the shell size is obtained. The shell does not have to cover or exceed the entire areola.
