These are scraps left over from production. I believe the type of wood is solid, but I'm not sure, so I'll list it as unknown. Various shapes are included randomly. They are cut directly, so the cut surfaces have not been treated. There may be chips, holes, knots, and insect damage. Please check the photos for the sizes. (Parts other than those in the photos may be included.) I hope you can use them for DIY projects, crafts, and educational toys. They will be placed in a plastic bag, put together in a cardboard box, and shipped via Yu-Pack (simple packaging). *Wood shavings may be attached. Please be aware of this.
