To use this fencing mask, simply put it on your head before starting your fencing session. Make sure it fits snugly to protect your face. When using it, be careful not to hit it too hard against other objects as it might damage the mask. After each use, wipe it with a clean, dry cloth to keep it clean. Store it in a cool, dry place to prevent any mold or mildew from forming. This will help keep your mask in good condition for a long time.
