To use this muzzle harness, first adjust the straps to fit your partner or pet's head comfortably. Put the harness on and position the ball gag in the mouth if you want to use it. During play, be mindful of your partner's comfort and safety. Don't over - tighten the straps. When you're done, remove the harness gently. To maintain the product, wipe it clean with a soft, damp cloth. Avoid using harsh chemicals as they may damage the PU leather, metal, and TPR materials. If you don't plan to use the ball gag, store it separately in a dry place.
