Unused item, only tried on. Silicone breast forms, C cup (felt like E-F cup). Natural skin tone, so it blends in easily. No zipper in the back, it's a pull-over type. Filled with cotton, so it's relatively light. 【Size】 Neck circumference: 32cm Upper bust: 81cm Under bust: 68cm Weight: 1.15kg I forgot the manufacturer, sorry m(_ _)m ! Immediate purchase welcome!
