XO is the new, innovative relock system for beverage cans. While new and revolutionary, the XO opening will still feel familiar to everybody: the XO resealable can opens like a traditional SOT (Stay-On-Tab) can, yet it includes what the SOT is missing: the ability to be relocked. Opening the XO-equipped can is an easy, intuitive and one-handed procedure. It’s the Relock Revolution for all canned beverages.
