Although there is no outer packaging, it is unused. This is a set of 3 items: silicone breast forms + dedicated protective cover + bra pads. It has a smooth texture, natural elasticity, and moderate weight to maintain body balance. The design aims for a natural fullness from the armpit to the breast, providing a comfortable fit. A recess is created on the back to reduce stuffiness during long-term wear. This product is a spiral type for the left breast, and the protective cover is a hookless type. 【Material】Breast forms: Silicone Protective cover: Cotton ※ Many people find the 400g and 500g sizes to be particularly large. Be sure to measure the healthy breast and choose a size close to it or one size smaller. If you are a first-time user or unsure, consider a smaller size. Please use it in conjunction with a bra. You can use your existing regular bra, even if it is not a dedicated pocketed underwear. You can use the breast forms as they are, but if you are concerned about sweat, dirt, or texture, please put them in the protective cover. The pads are for when there is a gap at the top of the breast or for adjusting the height and balance between the left and right sides. They can also be used alone.
