With the shoulder strap retainers in silk finish, the slipping of vest or bra straps is prevented when wearing sleeveless clothing. They are sewn into the shoulder area inside the garment. The straps are guided through the flap, which is closed with the press fastener. This allows even wider straps to be held perfectly in position. The shoulder strap retainers are made of 100% polyester and are equipped with a stainless press fastener made of brass. They are available in white, black or skin colour and on a card with 4 pieces or in the large pack with 1000 pieces and can be washed up to 40 degrees.
