This stylish and practical set includes a 20oz stainless steel tumbler with a slide lid and straw, and a Papermate gel pen with a refill. The tumbler is double walled and will keep drinks cold or hot for hours, though a straw is not recommended to use with hot liquid. And all of it is hand made with epoxy, so it is safe in the cured state. Get the matching set for your home or office today.
