I purchased this around 2005 or 2006 at a sporting goods store. I only used it to boil water for instant ramen and coffee. I used the small cup as a measuring cup in the kitchen, but I stored the large cup and lid in the original box, unused for about 10 years, in indoor storage. The outer box and the item itself have been wiped with alcohol, and the mesh bag has been hand-washed. There is a hole, about 2 cm, in the mesh bag. Please check the photos for scratches, dents, and heat discoloration. I will use the original box for shipping (Yamato Transport 60 size). If you would like the original box, please let me know in the comments. Due to the value of the discontinued item and shipping costs, I will not offer a discount. I do not offer holds. If you have any concerns about the product condition, please ask in the comments. Please apply to purchase after understanding the description and the condition of the product.
