Coffee - it’s not just bean broth. Some call it the water of life! Celebrate your favorite drink with the molecules that make it unique.

Nothing is a better thermal insulator than… nothing! This stainless steel flask’s double walls contain as close to a vacuum as you can get. Vibrating molecules like other molecules to bounce against - that’s how heat transfer works, like a cue ball bouncing around a pool table, transferring energy the other balls. When there’s nothing to bounce against, for example the vacuum part of the vacuum flask, the heat energy stays within the system! Thus, this flask will keep your preferred beverage at whatever temperature it starts, for a good, long time: 12 hours hot, or up to 24 hours cold!
