This is a pottery mug, by DeneenPottery.com. It is a beautiful - I think so anyway as I love green- handmade piece, and it's pretty heavy. It has a durable glazed finish with a comfortable handle, and is perfect for daily coffee or tea, and get this, it's microwave and dishwasher safe! It adds country cafe charm to wherever It is used, and would certainly be a wonderful gift to your favorite person! Handmade in the USA.
