These are molds used for making flowers out of clay. My mother imported these from Thailand during her time creating paper flowers. I don't know the petal shapes or the number of petals needed, so I can't provide detailed instructions on how to use them, such as which part is for the petals or leaves, as I am a novice. If you are interested, please feel free to use them. *There may be lines on the sides, possibly from the manufacturing process. *The packaging has some stains that cannot be completely removed. Please be aware of this. Returns and exchanges are not accepted. Will be shipped via Nekopos (a Japanese delivery service). Price is not negotiable.
