It's a great tumbler, keeps my coffee warm for ages! Really well, I was happy with how the marble effect turned out on the white!

Bought this and a few others over the holidays for presents, they loved them and commented how nice they were, they are great for the beach. Printing turned out great, crisp and clear

The tumbler was bought as a gift so can't say how efficient it will be as an item, but a good Grandad present. Pictures were originally from a mobile phone so the reproduced quality is very good
