I just received these today, and I am so impressed. I was slightly skeptical at first, because I have had 2 different sets of high-priced Amoena prosthesis in the past. I had my bilateral mastectomy 2 years ago. I have lost about 70 lbs since then, so I can no longer wear the Amoena ones. I can't afford another high end pair with my insurance deductible. I ordered 2 breast forms. The description and sizing of these breast forms seemed very high quality and straightforward. I ordered the 500g/Size C cup. I am 5'3", 133 lbs, and have been wearing a size 36D pocketed bra with cheap foam inserts. The forms each come in their own storage bag and include a nice soft fabric cover. The texture and shape of the forms are exactly as pictured and described. They fit perfectly in my bra with enough room that makes it easier to put them in/take out (since the bra is a D cup). I look like I had just been custom fit with a more expensive brand breast form. I wanted a heavier, realistic, waterproof breastform to feel better about my body, have something with natural flattering shape, and forms that will not float up when I use them in a bathing suit for water exercise. If you don't already have a quality one, get yourself a pocketed bra that fits well. Still measure yourself according to the directions. I also want to note that I have good coverage with these forms even with my scarring starting higher up on my chest wall. I would order more in a heartbeat. Well done with quality, softness, material, realistic weight, accurate sizing, bonus storage bags, nice protective pockets, and very helpful description and photos of the product. Would absolutely be a repeat customer and recommend. Fast shipping. Review: Nice - would buy again - These are heavy but work perfectly because I’m concave from a mastectomy and they rest on my rib cage. So, they look much more natural as the weight hangs them lower than the foam foobs. I don’t use them for everyday but when I go out or dress up they are perfect. And they feel kinda real. ## Features - Each breast form is made of medical-grade silicone, individually and expertly. creates an ultra-soft breast form with the most natural appearance and feel possible. - ONEFENG breast forms are used for mastectomy cancer patients, to support women’s confidence to live an active life after the diagnosis of breast cancer. - Our carefully-crafted, ultra-realistic, breast forms are designed for comfort and realism and have been perfected through years of experience and research on breast cancer patients. - Please make sure the item is in good condition, then please put the breast form into the pocket of your bra, adjust the position and angle to find the most comfortable feeling and the best look. - Hand wash in warm water with mild soap, air-dry or with towel gently.
