With the shoulder strap retainers in silk finish, the slipping of vest or bra straps is prevented when wearing sleeveless clothing. They are attached in the shoulder area inside the garment with the safety pin. 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 and a safety pin made of stainless brass. They are available in white or black, with two pieces on each card and are washable up to 40 degrees.
