High – class, very strong BB swivels in five sizes. Made from brass, with 2 welded rings. Good snap and bad snap – it can make real difference! For last years we have been working on our own snaps programme, aiming to develop products of the highest quality. After many different tests, we decided to use highest quality Swedish stainless steel wire with a very high degree of elasticity – 10270-3/X10CNR (non-alloy steel, cold drawn, resistant to corrosion), manufactured by Swedish company Sandvik AB. Nearly five times more expensive than wires commonly used for snaps production, is a guarantee of reliability and performance required to keep throughout the life of the product.
