I purchased my first item a courtly check mug $58 upon arrival there was what i thought was a speck of something on the inner lip so i washed it in sink and placed it in cabinet. Few weeks later i thought i would use cup for coffee and after drinking rinsed the coffee out saw a brown spot again only larger and spreading RUST - tried to contact MC customer service and emails many times - finally after months a response - their is no warranty sorry. A $58 cup has no warranty?! NO more for me
