airy flanges in translucent two-color red and blue polypropylene. Nipple shields (6 months+) of asymmetrical shape in rubber. Rings to attach-soother.
Advice: prefer the steam sterilization in a electrical sterilizer to than soaking in a disinfectant liquid which leaves a strong smell in the nipple shield.
Advantage: to buy by 2 allows to have an identical soother of replacement in the event of loss.
