The Changer is a 16 oz reusable tumbler with a silicone lid and a matching-color straw. Its body shifts color to match the lid once a cold drink goes in, which makes it a visible novelty rather than a plain cup. It is BPA free and dishwasher safe, so it holds up to daily use better than disposable cups. It suits people who want a fun everyday tumbler or a giveaway item; against plain insulated tumblers it trades heat retention and a sealed lid for the color-change trick.
