The Francois et Mimi Stacking Mug Set with Rack is absolutely perfect for anyone looking to save some space in their cabinet, or have a small kitchen with limited counter space like I do. These mugs and line of kitchen ware products remind me a lot of my fiesta ware that I currently collect. The pastel colors on the mugs are very vibrant and bright and are made out of a stoneware ceramic that is lead free. I love that this has a space saving design, and can be washed and cleaned in the dishwasher if need be or used in the microwave which is a plus in my book! The mugs can hold up to 11 ounces each which is quite a bit when it comes to coffee, tea, or hot chocolate. I love that the holder appears to be stainless steel, but may just be some type of metal. Each cup has a beautiful insignia on the bottom representing the Francois et Mimi company. I love their product line very much and hope that I can collect more of there colorful kitchen ware to match my mugs. These definitely get 5 stars in my book.
