Nipple Protector available sizes
The Nipple Protector is available in two different sizes. The standard size has a diameter of 21.6 mm and the small size has a diameter of 14.9 mm. The diameter is measured on the base of the protectors, see the picture below.
Note: The size depends on the size of the mammilla (nipple) and not the size of the areola. If the nipple has 2 mm of leeway, this is your correct fit.
Note: if in doubt, we recommend that you seek advice from a Health Care professional to find the best size for you.

How to check if you have the correct fit
- Apply the protector over your nipple
- If centred correctly, there should be 2 mm of space between the nipple and the side and top of the silicone nipple shape (see the image below)
