I am a breast cancer survivor and have had prosthetics that are incredibly heavy and hard on my neck and back. Other foam or fiber have been too light and do not stay in place in my under garments. These have a little weight. Good form and the price is 1/10th of a cancer prosthetic! I came a crow this store a year ago and Daija helped me was kind and emphatic! Truly a lovely person who made my experience pleasant! I recently bought replacements, and drove from Canada to support the store! Thanks Wink wink you have a loyal customer!
