These are 50 round nipple covers, which are more noticeable than the new flower-shaped ones. They are disposable, so there's no need to wash them. If you prefer thicker pads, these are also OK! They prevent nipples and areolas from peeking out from cosplay costumes. They also help prevent visible nipples when bending over or raising your arms, and protect against chafing from clothing. During this time of year, the inside of your bra can get stuffy, and your nipples might get itchy or develop heat rash! Nipple covers can help alleviate those issues. They are breathable and the adhesive is less likely to cause irritation. They are water-resistant, so you can use them with swimwear, but they may come off. Silicone ones are better for swimwear. I also have round & flower-shaped silicone ones available, so why not try using them differently? Please note that there may be slight color variations depending on the manufacturing date. ps. If you need more, please contact me via comments. I will prepare them as a separate listing!
