Dutch Bros Logo Cup Prototype Winter Design Coffee Tumbler Travel Mug w/Lid 16oz. This is a sample/prototype metal insulated mug that never went into production.  The person I got this from worked in product design and is not aware of any other cup exactly like this. It is 12 oz, and has a cool screw on lid with an open/shut cover for sipping or a straw. Has a windmill, cool winter inner tube scene. And an OG Dutch Bros logo. Great condition. About 7" tall.
