Poured iced coffee in and the whole cup turned this deep teal within seconds, which honestly made my morning. The 17 oz size fits a full can of soda with ice, and the frosted fluted texture feels nicer in my hand than I expected.
Didn't expect the color change to be this dramatic, but watching it shift as soon as the cold drink hit was genuinely fun. The 17 oz size is just right for a full glass of water, and the fluted frosted look feels nicer in hand than my old plain tumbler.
