One Touch Delica Lancets Device features a new, proprietary 33 gauge lancet that is 40% thinner than current industry standard 28 gauge lancets. In addition, the system's Advanced Glide Control System precisely guides the lancet in a swift, straight motion that reduces vibration for a smoother lancing experience. It also features seven adjustable depth settings to allow for shallower fingertip punctures that may be less painful.
