I have been using Tervis tumblers at the cabin to keep drinks cold on the pontoon for years but didn’t know they made a handle and cover for them. What an amazing add-on! Allows you to comfortably hold the tumbler without worrying about spillage or the tumbler slipping out of your hand.
Tervis tumblers are double-walled insulated and some with a lifetime guarantee. A great drinking “tool” made in America since 1946.
