This 20 oz Skinny is made from durable stainless steel to give you a firm, comfortable grip on your cup to keep you from spilling! These Tumblers include a double vacuum wall insulation to keep your beverage fresh. It keeps drinks hot for hours, keeps ice from melting, and keeps drinks cold. You’ll never have to worry about your coffee getting cold again! The sturdy clear lid keeps an air-tight close on your cup, reducing the risk of spillage, and the lid’s transparency will show you just how much is left in your tumbler. The double wall technology keeps your drink from forming sweat on the outside. Messy, slippery condensation will never ruin your coffee tables again after purchasing one of these. Please note, that due to the custom finish of our cups, they will need to be hand-washed. These tumblers are fit for travel, so you’ll be ready for adventure at anytime! And all for an affordable price too!
