SSK case included. O size: 3 pieces L size: 3 pieces M size: 2 pieces All are for both ears. The case string is cut (see photo 2). The shoulder strap can be used without any problems. Used for about 15 games. After use, I clean them and store them in the dedicated case. The helmets still have a shine and are in relatively good condition, but there are some minor scratches, so please consider only if you understand that they are used items.
