The Braza Bra Strap Comfort are silicone cushions that you slip your bra straps into for immediate comfort. They can eliminate bra tug, deep grooves and discomfort by more evenly distributing weight. They can also prevent your shoulder straps from sliding off during the day. They’re made of 100% silicone so they’ll last through many wears and are very easy to clean. Maximum bra strap width to fit inside is 1.25in.
