I purchased this Hario glass ring at a store in Lucua Osaka. The size is 12-13, as indicated on the box. I've used it about 10 times, and there are no noticeable scratches or stains. All original accessories are included, but the warranty card has a cut in it from the time of purchase. Please refrain from purchasing if you are looking for a perfect item, as this is a personal item that has been stored by an individual.
