✔ DOUBLE LAYER FOR BETTER FEELING & PROTECTION : Unlike other nipple band, Our bands are made from double-layered bands by adding gauze for sensitive nipple areas. ✔ 0.8 INCH DIAMETER OF GAUZE INSIDE : The diameter of the gauze inside of the band is 0.8in(=20mm), so it effectively covers almost all chest sizes. ✔ SAFE ADHESIVE FOR YOUR SKIN : Used with non-irritating adhesive gel for sensitive skin, which leaves almost ZERO adhesive residue when removed. ✔ SMOOTH, STRETCHABLE BUT WITH EXCELLENT ADHESION : The material is smooth, stretchable, and has excellent adhesion. ✔ VENTILATION : The entire band is ventilated, so your skin can breathe sufficiently. ✔ LONG TIME USE : You can use it comfortably for long periods of time because it is not easy to sweat-off. Don’t take our word for it – try it for yourself. We think you’ll notice the difference! * Please be aware that this nipple guards band was intended and most optimized for men's nipple.
