The Contour Blood Glucose Test Strips by Bayer has 100 test strips total(2 boxes of 50ct). Contour uses a bottle design with an already built-in desiccant, which removes all the moisture so the test strips stay fresh for up to six months after opening. Using a Sip-In Sampling technology, the Bayer Contour test strips feature a convenient window that makes it simple to see when the test strips are filled with blood.
