White's Tree Frogs, Dumpy Tree Frogs, or just plain Green Tree Frogs in their native Australia...whatever you call them, these adorable little guys are tremendously popular as pets and on our illustrated tumbler. These 20 ounce, insulated, stainless steel tumblers are an excellent way to keep your drinks hot or cold, and in style too! They hold heat and cold well (we actually recommend letting hot drinks cool to be drinkable before putting them in the cup, that's how well it insulates!), are extremely sturdy, and are dishwasher safe, straw, lid, and all! It is recommended to place the lid in the highest shelf of the dishwasher. Each cup comes with a plastic sip lid and a stainless steel straw.
