Review: Good value for money - Not expensive for what it is ime a 36 C cup and it's not too heavy the one I was fitted for was quite heavy and a bit big this one seems ok probably not as well made but probably a quarter of the price I would order again as it does the job

### ⭐⭐⭐⭐⭐ Review
*by N***R on 7 January 2026*

ELATED! 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.
