These are tools for making decorative salt piles (mori-jio). White, ceramic. Please refer to the size in relation to the hand in the photo. You can make octagonal pyramid-shaped salt piles. Originally used by my parent, but they got bored after using it 2-3 times and it's been stored away since then, so it's relatively clean. I myself have never used it, so I don't know what it's like to remove the salt from the mold, nor do I know if it works well depending on the type of salt. If you are someone who often uses these types of tools, or knows a lot about them... please consider purchasing. Of course, those who are interested in making salt piles are also welcome to purchase.
