Introduced in 1979, the "Happy Holidays" holiday pattern from Nikko has become a seasonal classic, with its swirl fluting around the edge of each piece. Made of high-quality Japanese ironstone, the pattern has the classic Christmas Tree decoration on each piece, and offers a full range of place setting and serving pieces, as well as collectible giftware. The entire range is completely dishwasher and microwave safe. The flair shaped coffee mugs are sold in a giftboxed set of 2, and have a 10-ounce capacity.
