This package of Twist Top Lancets has been designed for use with Prodigy Blood Testing Glucometers but will work with most other lancing devices. Use these lancets as they are or with a lancing device (available separately). Each lancet features a twist-top, an ultra-fine gauge and tri-bevel tip. To use, twist off the protective cap. After use, discard the lancet in a puncture-resistant container. Thanks to the tri-bevel tip, sampling is virtually painless with these lancets. These Prodigy Twist Top Lancets penetrate the skin every time and offer consistent depth penetration. Do not store lancets in lancing devices and do not reuse lancets. Lancets are packaged sterile with a protective cap. Do not use if protective cap is missing or damaged. 100 lancets per box.
