The Tea Sub is for that avid Beatles fan in your life that happens to also enjoy a spot of tea. Designed by Ototo, this yellow submarine submerges into the boiling hot water in your mug and then magically transforms it into the tea of your dreams. All you have to do it fill it with your favorite tea leaves.
As a tea-drinker myself, I appreciate that Ototo is trying to make tea time more playful and fun with the creation of the Tea Sub. I'm sure the Beatles would approve.
