In 2002, after years of research and development, Bragel revolutionized the conventional bra with the innovative NuBra. This strapless and self-supportive bra has a specially formulated PSA adhesive, which has been clinically tested to be safe and skin-friendly. The unique PSA adhesive, once washed, regenerates its stickiness and offers its wearer more than 100 times of normal, repeated application. NuBra is comfortable, versatile, and user-friendly. NuBra is also highly practical and convenient, as it can be used in a pool or in the shower, while remaining secure. This incredible product essentially eliminates the adhesive tape currently marketed in the lingerie industry.
