Natural rock salt plate that brings out the flavor of ingredients, perfect for grilling. New, unused, and unopened, but has been stored for a long time. I bought this after using it for dinner at an onsen (hot spring) and finding it delicious, but I haven't had the opportunity to use it at home, so I've been storing it. I hope you can use it for BBQs, etc. - Product Name: Rock Salt Plate - Features: Brings out the flavor of ingredients - How to Use: Perfect for grilling - Size: Approximately 13cm x 7cm x 2cm - Material: Natural rock salt Thank you for viewing.
