Most people don't measure out their milk when adding it to their coffee. They generally just pour until the "right" amount has been added. If you've ever tried to be helpful and make someone a perfect cup, you may have found that it was either too much milk or not enough. Wouldn't it be great if there was a way you could figure it out? Well, now you can thanks to the MyCuppa mugs from Suck UK. Inside the mug are a series of color strips. All you have to do is find out what color they like, and then pour the milk until it matches. At little under $15 a piece, these mugs — available in tea or coffee versions — would make a great gift, or would be a great starter for that novelty mug collection you've been meaning to start.
