These are blocks that were included in a math set. Set of 3 These were used by a child in elementary school, so there is some wear and tear. Please check the photos. There are no names written on them. If you've lost some or need extras, how about these? 17 blocks remaining I have more in stock. Individual sales and bulk sales are possible. I haven't listed them, so please consult with me in the comments if you need any. The cardboard pieces have names written on them, so I will black them out.
