Clean Bottle Square

While many water bottles are built to last a lifetime, cleaning the depths through that narrow spout can be tricky (read: impossible), ultimately resulting in the accumulation of some pretty nasty funk deep inside. Clean Bottle’s Square solves this with its twist-off bottom segment, making it easy for you or your dishwasher to get to every last corner. Add in a wicked shape, a plastic lip and a lifetime guarantee, and the makers of Square can have our money.
