Gobelet Magique Licorne

The opalescent finish looks even better in person – it shifts colors whenever I move the tumbler. I've had iced coffee in it for hours and the chill holds up way longer than my old cup.

I was skeptical about the ice retention but after leaving my iced coffee out for a full workday, there was still ice cubes floating at 5pm, plus the finish looks even better in sunlight than in the photos.

That opalescent finish catches the light so prettily I almost don't want to put it in my bag. The cold retention is legit too—my water stayed icy through a whole afternoon of errands.
