Some travel mugs also come with removable insets, which allow you to shave or cut your coffee without having to take the whole thing out of the mug. This feature is great for people who love doing their own thing, but who don’t want to deal with hot liquid when they’re away from home. One can remove the inset and re-insert it back into their travel mug without any problems. These mugs are also often insulated so that the hot liquid stays inside and doesn’t have to be warmed up outside of the travel mug. These mugs can make great travel companions as they will keep the drinks hot and fresh until you get back to home.
