Mug Set. While these look like ordinary mugs, they have added function you don't normally find. These mugs come with a travel lid so you can take them on the go or just transport your drink around the house with confidence. They also have removable cork bases which help with insulating temperature and protecting your surfaces from scratches and stains. To wash, simply remove the cork base and wash by hand. The mug is also microwave safe so long as the lid and cork base are removed. Complete your kitchen with these cozy spill and scratch resistant mugs today!
