OpenX is the original Universal Dual Blade Package opener designed to open those difficult plastic packages along with most every type of package. Great for boxes, express envelopes, shrink wrap on water bottles, pill containers, snack bags and more! The unique dual blade design allows you to use the retractable blade to pierce the plastic and then insert the hook of OpenX to Push and Slide to Get Inside. The retractable blade is short so when cutting open boxes, you wont cut the contents inside.
