This classic red ball gag is perfect for your classic bondage scenes! Non-toxic natural latex mouthpiece is a comfortable 1.75''(4.45cm) in diameter, so it fits most mouths. Thick oil-tanned leather strap is resistant to bodily fluids and has smooth, finished edges that won't cut into sensitive skin. Strap fastens with a buckle; entire gag measures between 15'' - 22'' (38 - 55.8 cm) when fully closed. (Keep in mind that gags go around the neck, not the widest part of the head, so your gag size is different than your hat size.) Not safe for latex allergies. Hardware is nickel-plated for strength.
