40-ounce thermos for cold drinks

Glad that I found a 40-ounce thermos that was reasonable priced and loved the color it was available in and large enough for my tea or water. Very nicely made and well insulated for keeping your beverage cold.

Great cup, just watch the handle...

Really good cup, but I didn't have it long before the handle came off. It doesn't affect the cup itself, but I was disappointed that the handle came off, and I didn't even have it a month.
