Mug Stacker is an adjustable stacking device that helps you easily and conveniently store and organize your drinkware.

Mug Holders take advantage of all that unused airspace inside kitchen cabinets between your mugs and the shelf by lifting your cups, mugs, and glasses on top of each other without the risk of chipping or breaking them, utilizing the area that would normally go to waste. It’s like discovering a whole new cupboard.

The Mug Stackers are totally adjustable, so no matter what size your cups happen to be, it’ll give you space for more dishes, more glasses, and more of whatever you need to stash.
It's very easy to use; just place one Stacker on top of a glass, mug, or cup, then set another one upside-down, right on top.  Give the Stacker a little squeeze to adjust to the size, and your drinkware is safe and sound in just the right amount of space.
