One box containing 100 pieces. These were used on the chalkboard for amateur baseball. This is an unused item, apparently from the Showa era. It was stored in a storage room. When the top lid is opened, the sides are protected with styrofoam, but due to the nature of the product, it is prone to chipping, so please be aware of this. If you wish, I have another box available. The price will be different, but please feel free to inquire.
