As the leading supplier of breast forms worldwide we wish to help you restore your confidence and feeling of femininity after a mastectomy or lumpectomy.  Our prostheses can help provide a balanced shape post surgery and help provide a temporary solution between the time of reconstruction surgery or offer a permanent solution.

Our triangle breast forms are our most popular shape.  The lightweight breast prostheses have been designed for comfort, they are made from 0.22% foam powder and 99.78% silicone with a TPU (plastic film) outer covering providing you with a lighter alternative to the full, silicone breast forms. 

Our triangular breast form is a full breast shape which will fit many types of breast shape, they are symmetrical so they can be worn on either side.  The triangle shaped breast forms work perfectly for women with round and full breasts (known as Archetype) and Athletic breasts (breasts that have more muscle and less breast tissue).  Our triangle shaped breast forms are also a popular choice with crossdressers.
