I have around 70 travel mugs from a student event looking for a home. I’m going to try homeless charities as a suitable home. They should be ideal for that sort of thing. They are branded with the American Express logo but I don’t think that matters. They are all brand new unused mugs.
There is one damaged one, it escaped the box and hit every single step on the way down the stairs at work, bounced off the wall at the landing and made its way down the rest of the stairs. It did crack but they are pretty strong.
