You know that cupboard above your sink that has a collection of metal and plastic travel coffee mugs that may or may not be missing any/all of their matching lids? Throw them all out (unless they’re recyclable, in which case do that). You don’t need any of those free plastic bank mugs, metal coffee shop mugs with malfunctioning heat seals or any of the mugs that could potentially fall over and ruin your work. The only mug you need from now on is the Mighty Mug. Inspired by tree climbing frogs and octopus tentacles, Mighty Mug uses patented Smartgrip Technology to create an airlock between your mug and whatever flat surface you place it on–without making it difficult to pick up vertically. Each Mighty Mug is made out of BPA Free plastic or stainless and there are five different size options depending if you want standard coffee, Keurig functionality or iced beverages. They come in a number of different colors and will pay for themselves within a month if you skip coffee shop trips and brew at home.
