Thank you for viewing. I am listing this item because I haven't had the opportunity to use it. These are two coasters purchased as souvenirs about two years ago from Awashima, Niigata. They are made from marine plastic waste. After purchase, they have been stored on a shelf in their original packaging. This is a set of warm and cool colors. Discounts are available if you purchase with other items I have listed. Thank you for your consideration.
