You know that scene in movies where a character has a sudden realisation and their coffee cup dramatically slips from their fingers and crashes to the floor? That in theory would never happen were the characters using these Crux Mugs, which employ an artificial climbing hold for the handle.
Depending on which $16 design you buy, you’ll have to learn to get used to holding your coffee in weird new ways. But the payoff is that no natural disaster, nor dramatic revelation, will ever wrench your coffee from your hands.
