6"dia x 7"h Happy hour is about to last a whole lot longer—up to four hours, in fact. It’s all thanks to these insulated stainless-steel stemless tumblers, which have a removable glass insert to keep your wine cooler for longer and fend off pesky metallic flavors. You can sip easy knowing the lid on top has a sliding closure that’s happily spill-proof. And when the festivities wind down? Just pull the glass lining out with a twist and send it through a cycle (of course it’s dishwasher-safe).
