This is what we would call the “Wonder Tumbler”. It holds both hot and cold liquids. That in itself is a wonderful convenience. It is virtually unbreakable…dishwasher safe…microwave safe… reduces condensation, and of such high quality since 1946, that it has a Lifetime Guarantee. It also has a great appearance. A little green embroidered emblem is actually attached to the tumbler. It holds 16 oz. of liquid.
