Each SEI MIO Handi-Cuffs Medium is crafted from pliable, odor-free silicone that feels silky against the skin. The material has just the right amount of stretch to slide on smoothly yet resists sliding off unintentionally. The medium cuff opening measures about 2.5 inches in diameter at rest and expands to fit up to a 9-inch wrist circumference, making these silicone restraint cuffs a versatile choice for many users.
Care & Safety Tips
Rinse cuffs with warm water and a gentle soap after each session to remove body oils and residue. Air-dry away from direct sunlight. Always check for any signs of wear before use. Do not use on irritated or injured skin, and ensure that the restrained person can communicate freely at all times. For prolonged play, take breaks to maintain circulation and comfort.
