I received this as a gift from an acquaintance a while ago. I thought I would use it someday, but it ended up sitting on the shelf, so I am selling it to declutter. It is unused, but the outer box has a slight bulge. There are no problems with the box itself or the contents. The following information was referenced from the website. The color of the outer box is blue. Please refrain from purchasing if you are concerned as it has been stored at home. Thank you. "This is a set for comparing the taste of Japanese sake. It is said that the tin sake vessels mellow the taste of the sake because the tin ion effect removes impurities and refines the taste of the sake. Please drink the same sake from the same shaped glass sake vessels. You can enjoy different tastes with each sake vessel. NAKAGO's tin sake vessels are handcrafted with unique processing. Therefore, they have a shine that is not found in other tin products. The glass sake vessels are cool and have a slightly rounded shape. Although they are the same shape, the material makes a difference in the mouthfeel and taste."
