I am a McDonald's owner and bought these years ago for a promotion. These are plastic travel mugs that never sold during the promotion. I am retiring in 6 months so they must go!
See last 3 photos for how the mug looks. It comes with a lid that fits in snug and tight and a base to attach it to.
It holds about 16oz.
Help reduce single-use cup waste with this reusable mug!
