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.

Great product

These things work just as promised. The thing I like the most is that they don't sweat. Our humidity is usually so high that a regular glass of anything cold will form a huge puddle. These keep the drinks cold and leave no condensation rings.More > < Less


Keeps the brew cold

I love this for my first beer of the day. On a hot day, there is nothing like a cold brew, especially out of one of these tumblers. It feels nice to drink out of and to hold. And cleaning is a cinch....wide enough to fit a regular scrubber into and dries so fast you can put it right back in the fridge or freezer. My only wish is that they would keep cold longer. After the first drink, it’s only as cold as the surrounding air.More > < Less

Work great. Only problem is they chip easily at the drinking edge. Not sure why


Works well, looks good

Works well but you have to keep it under cold water for at least sixty seconds to make sure it stays cold enough to last through a 12 ounce beverage.


So far so good

About Magisso

Simply Brilliant

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.
