心情杯

Poured cold water in and the whole frosted cup shifted color right in front of me, which honestly made my afternoon. The 17 oz size means I'm not refilling every ten minutes, and the fluted shape looks nicer on my desk than my old plain tumbler.

The fluted sides make it easy to grip even when it's sweating, and the 17 oz size fits a full can of soda with ice. Watching it shift color as the cold hits is honestly the best part of my afternoon.

Poured iced coffee into it and the frosted fluting turned this deep blue within seconds — seriously fun to watch. The 17 oz size fits a full can of soda plus ice without spilling, and it doesn't feel flimsy in the hand either.
