I am selling silicone breast forms purchased on Amazon. The brand is unknown, and they are E and F cup size. They do not have a zipper. They are lightweight because they are filled with cotton. I bought them for cosplay, but I haven't had a chance to use them, so I'm selling them. I have worn them once or twice over an undergarment, and I have washed them and applied baby powder before storing them. I will wash them again and apply baby powder before packing them for shipping. Due to the nature of the product, they tend to attract lint. I will do my best to prevent this, but please be aware that it is possible that some lint may still adhere to them when you purchase them.
