Review on Set Of 2 Pink 12 Oz Double Wall Vacuum Insulated Stainless Steel Wine Tumblers With Lids, Including Straws And Brush: Perfect For Wine, Champagne, Cocktails, And Travel Coffee Mugs by Michael Pickering

I bought these because my cat has taken to drinking out of my water glasses and wanted something insulated, mostly metal and with a lid to prevent this from happening. The tumblers are of a good size and work well. The insulation is decent, not the best but keeps my water cold for a couple hours. The tumblers look nice and seem durable. The only issue is the lids are a little loose and when knocked over, they will pop off if the tumbler is more than half full. Not an issue for me, however, if you're buying this to prevent spills then be aware that other brands (like S'well) have much tighter fitting lids.
