Roll-type finger cots (rimmed finger cots) feature a rolled edge that allows the cot to be easily rolled from the fingertip down to the base of the finger, helping it stay securely in place during use.
Rimless finger cots (cut-type finger cots) are designed without a rolled rim, providing a smoother and lighter fit. Many users prefer rimless anti-static finger cots for improved comfort during long working hours in cleanroom and ESD-sensitive environments.
