I'm Not a Paper Cup looks just like paper but is made from 10 ounce biodegradable plastic. With a screw on slide open/close spill resistant lid and the ability to fit in most corporate coffee machines I'm Not a Paper Cup will help you say I'm not hurting the environment. As a promotional tumbler it is lightweight, has a large imprint area (the TM-10 includes a one color imprint and setup with multi colors optional) and contains no BPA providing a safe alternative to regular promotional cups. This tumbler is also available in a 16 ounce version I'm a Paper Cup...Not!
