I’ll finish it later
How long have we lived with this problem? Once you open a can of soda, you are committed to drinking it entirely or throw it away with liquid still inside it. Okay, it’s never a big serving, but sometimes you do want to save at least something for later.
With a bit of creativity, people created this fantastic lid to do just that. Store your beverage for later. It is also such a clever design that we are baffled that this is the first time someone thinks of it. Such an easy solution for such a simple problem.
