Gel Petals have become very popular, but there are still many women that prefer a disposable version. Most disposable nipple covers on the market are made of a rigid or non-woven material that does not stretch to bust shape and does not meet our standards for safety, comfort, and reliability. Braza nipple covers are made from a knitted material that stretches and conforms to the breast shape so there are no wrinkles or telltale edges to show through clothing.
