Perfect gift for that special grandad in your family. This mug is 5 1/4" tall and big around. It is double wall insulated with a nice tight black lid. It is in great shape, he will love using it at home or travelling. If you would like to come and see it give me a call at 613-542-1186. Thanks for checking it out be sure to check out my other ads.
