Ceramic I purchased this item, but ended up buying a different size, so it has been stored at home unused. The original box has become old, so it will be shipped in a different box. This is a lidded jar convenient for storage. You can store pickled plums, takuan (pickled radish), kimchi, homemade sauces, candies, and more. It's a mini size, so it can be placed in the refrigerator and is easy to wash by hand. Made in Japan, Tokoname ware, for peace of mind and safety. The black glaze drips are painted in three places, and each one is different because they are hand-painted by artisans. ■Size: Diameter 14cm x Height 15.8cm Inner dimensions: Opening diameter 11.7cm x Depth 12.8cm Capacity 1,440ml, Weight 865g ■Production: Made in Japan, Tokoname ware (Yamagen Kiln) ■Color: Amber ■Material: Ceramic ■Not microwave safe, not oven safe, dishwasher safe ※Please note that there may be individual differences in size, weight, capacity, and color.
