Natural walnut building blocks. My daughter used these, so there are some minor scratches, but there are no cracks or major dents, and they are relatively clean. Please check the images. She wasn't a child who played with building blocks much, so there are no bite marks, etc. These are Sound Blocks, which also have parts that make a shaking sound. The name is engraved on the third image.
