Optima Matte Surface Travel Mug - BPA Free. This travel mug has a silky smooth finish that looks great with a colorful custom imprint or logo. Using travel mugs saves you money in the long run that would have been spent on bottled drinks. Why pay for iced tea or water from the store when you can bring some from home and keep it fresh in your custom coffee travel mug? While bottled water has been all the rage for the past ten years or so, all of those individual plastic bottles can be taxing on the environment if they aren't recycled. Using promotional travel mugs is an excellent way of going green and saving yourself precious dollars at the same time!
