This is a silicone mold set. I bought all of them at a 100-yen shop except for the one on the bottom left. The shape on the bottom left was purchased at a parts shop and is unused. (8mm sphere) These are used items that have been used several times. It has been about 2 years since I last used them, so there is discoloration due to the passage of time. They are fine for use, but there are some areas with a slight feeling of use. They have been stored at home, so please purchase them with your understanding.
