Bombers Moulded Mullen Full Cheek New innovative mouthpiece from Bombers - thin 15mm thickness £101.00 Quantity: at £101.00 each Add To Basket New for 2019 from Bombers. Bombers moulded mullen Full Cheek has been uniquely shaped and flattened. It is angled at 45 degrees to offer an exceptionally soft and evenly distributed pressure over and around the tongue. The full cheek is a fixed cheek. Everything remains more still in the mouth, and if a horse is lacking in the confidence to stretch into the contact, this may prove extremely beneficial. Especially good for the horse that objects to metal or when you have tried every kind of bit without luck.
