You can hear the good vibrations that come from the Soundwave tumbler. This 2 7/8″ x 8 1/4″ drinkware is made of single-walled stainless steel, and holds 16 ounces of liquids. The outside is accentuated by our soundwave graphic scheme, which can be reproduced in four colors – and is matched by the plastic liner on the tumbler’s interior. It also sports a secure, twist-on lid and sliding lock to prevent spills. Add your business logo or message to this tumbler to make your customers take notice. This promotion is a great pairing with music retailers, tech stores, gyms and many other businesses.
