I can add approximatley 23 book titles on these tumblers. Just message me! I have pictured below one I did with some of Helen Hardt books on it.
• Kitchen-grade stainless steel, rust-resistant
• Vacuum insulated: 20 oz. tumblers are double-walled and vacuum insulated stainless steel, which keeps your favorite beverage hot or cold for hours
• Keeps drinks cold for 24 hours, and hot for 12 hours
Each tumbler comes with a plastic straw.
