No, this isn’t a giant soy sauce bottle, although you can use it for that as well. It’s actually a water bottle inspired by those small, single-serving soy sauce bottles that they give you at most Japanese sushi places. It can hold up to 500 ml of your drink of choice and comes with a strap so you can guzzle soy sauce, er, water when you’re on the go.
If you’re bored, just fill it with coffee and take it with you to the office. That should be fun (and it should also ward off would-be freeloaders from drinking your stuff.)
