Medela's TheraShells TM are a redesigning of the old Hobbit Breast Shells TM(pictured). They have a smaller firm plastic shell with air vent holes just in the top so any dripping milk doesn't go all over. It comes with two sets of inner rings - one for flat/inverted nipples and one for sore nipples afterwards. They are very small and discrete.
Price: WAS $15.99 - NOW $12.79
