Because the tumbler is composed of 18/8 kitchen grade stainless steel, it is resistant to rust and punctures. Because of the sweat-free design, hands and surfaces will remain dry. Print a wrap imprint, one side imprint, or two sides (please specified on PO). Don't fall for less expensive knockoffs. Temperature retention with copper liners might increase by up to 2 degrees per hour! complies with Prop 65. Diameter: 2.834" x 3.9" D x 7.8" H
