The Butt Cup: A Travel Mug With a Twisting Silicone Lid Like an Aperture

Sometimes something's so unique and weird, that even though it's not exactly more useful than other similar items, you just want to use it based on it being a pure oddity. This unique travel mug is just that. It's called the Twizz travel mug, and it has a very different type of lid that's made from silicone, and you twist it to close like an aperture.

Versions: Travel Mug | Lunchbox

Designed with a silicone top, the Twizz travel mug works by simply twisting the top part of the mug until the top closes in like an aperture. As you twist the lid, it'll click to lock in place at different intervals which allows you to keep it open at you preferred size. Once fully closed, the aperture lid gives it a compete water-tight seal.

To open the lid back up, just push up and twist the lid the opposite way. Pushing up on the lid will release the lock, allowing it to easily open back up. The unique silicone membrane lid allows for drinking straight out of the cup, or with an included straw.

The Twizz travel mug is microwave safe, dishwasher safe, and freezer safe, can hold up to 12 oz of liquid, comes in a few different colors to choose from, is made from bpa-free plastic along with silicone, and will keep drinks hot for up to 2 hours, and cold for up to 6 hours.

Not only is there just a travel mug with this weird and unique membrane lid, but there's also a small lunchbox container that uses the same aperture lid. The Neolid Lunchbox as so it's called is perfect for bringing leftovers to work. They both have such a unique design that they're sure to be an instant conversation starter (if you're into that kind of thing).
