Tasteful travel tumblers I purchased 3 of these, one for our soccer coach,and the other two for the two team managers. I received them in time for our team party by ordering 3 weeks before the party. Since these are gifts, I can't tell about how the travel mug works, but each of them turned out nicely and I love the stainless steel inside. I can't wait to present these at the team party since each has his/her name on it and I picked different designs and color schemes.
