Gustav Sweet iron Mouthpiece goes with the Otto combination bit. When you order a mouthpiece for your combination bit, please select a size that's 1cm larger.
Please understand: We make the mouthpieces just for you once you order. So, you can't return or exchange them. We create them from our standard loose ring bits to fit your needs. This lets us give you a variety of mouthpiece options and sizes for your custom bit!
