Perfect for my 22oz tumbler. No leaks (just make sure to hold the cap on when you shake your drinking since it has no seal around it. The shaker lid has a rubber gasket (which the top cap also needs) keeps the lid tightly sealed, however.

Very well made. Fits perfectly with the 22oz tumbler. Glad i putchased

This is so handy. I can turn any tumbler into a shaker! I really like using it on my holiday ones and making seasonal drinks.

Yes I like it a lot

Every cocktail shaker I’ve ever owned has leaked when I shake. Not this one! It’s perfect when paired with a Swig tumbler and makes for an easy, ice cold drink. Can’t wait till they’re back in stock so I can order more as gifts.
