I haven't used it at all, and there are no noticeable scratches, but please consider that it has been stored at home, so please understand the minor details. You can drink various alcoholic beverages such as wine, shochu, lemon sour, beer, and whiskey highballs while adhering to the daily intake. It's been sitting in the back of the shelf, so if you're concerned, please wash it before using it. I gave it to a friend two years ago, but they refused it.
