Say cheers to ceramic tumblers that keep beverages perfectly chilled. Submerge the tumblers in cool water to activate their natural cooling properties. This ceramic absorbs the water quickly, leaving the surface dry, so there’s no condensation, inside or out. Your drinks stay cool for hours. The matte surface is sophisticated and also acts as a chalkboard if you want to write on it.

What is Grommet?
● Since 2008, Grommet has been the place where you get more out of shopping small—from finding ingenious products you never knew about to supporting small bizzes that might be right in your neighborhood.
Magisso is a Finnish design collective that creates simple, beautiful solutions to everyday problems—and they’re constantly winning awards for their designs.
Their iconic cake slicer is a whole new approach to cutting and serving. Push the loop down to cut a neat, perfectly sized piece. Squeeze and lift to serve. No need to balance the slice as you move it to the plate.
That same brand of thoughtful innovation transforms beverage chilling with Magisso’s naturally cooling ceramics. Submerge them in cool water and the porous surface absorbs it quickly—almost like magic—and the outside becomes dry.
With the cool water inside, your chilled beverages stay cool for hours without needing ice. Plus there’s no condensation dripping onto your hands or table. The matte surface is an aesthetic and functional detail, too. It looks sophisticated while doubling as a chalkboard.
We can’t wait to see what simple, stylish solutions the Magisso team will come up with next.
