My water

Drinking your own water sounds simple,but drinking your own water at an outdoor event or at a gathering with friends can be a challenge. Because the water bottles we drink from are almost always the same, it can be difficult to tell which one is ours. The solution was to redesign the cap and the "anti-theft ring" underneath, adding white dots and 24 English letters. Users can rotate the "anti-theft ring" to make the white dot on the bottle cap correspond to the letter, according to their choice of letters for auxiliary memory.Such as initials, nicknames, lucky letters,etc.
