The PortaVia Universal To-Go Lid does something quite marvelous. It retrofits onto the top of any drinking vessel (mugs, cups, glasses, usually have roughly the same diameter at the lip) and instantly turns it into a travel cup that you can carry around with you without splashing your drink. It covers the mouth of the drinking vessel almost entirely, not only creating a nice seal that prevents spills, but it also helps in retaining your drink’s overall temperature, keeping your beverage hot and piping for longer, and if any of this wasn’t good enough, the PortaVia lid even comes with an integrated sipper that lets you use the cup and lid together like a travel mug with a sipper lid. The PortaVia Universal To-Go Lid is made from food-grade BPA-free silicone. It can withstand hot temperatures, it’s dishwasher-safe, and most importantly, it grips particularly well, creating a robust seal around the edge of your mug. Designed for most mugs between the 12-20 fluid ounces, the PortaVia sits snugly on top, almost like a Tupperware lid, turning a regular cup into a cup you can walk (or even run) around with, without worrying about your drink going cold, or worse, spilling. It also makes sipping your drink on the go easier, and is a much better alternative to disposable plastic lids. Plus, the fact that the PortaVia sits so wonderfully on ceramic and glass mugs also helps reduce your dependency on plastic or paper cups. The PortaVia, with its silicone construction, can be used and reused multiple times across almost all cups, mugs, and tumblers. It’s dishwasher-safe, food-grade, stain and odor-free, and also a boon for the planet! Designer:
