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. Are you missing some, or do you need more? Remaining blocks: 14 See photo 8. I also have rails, cases, etc. in stock. Individual sales and bulk sales are possible. I haven't listed them, so please contact me in the comments if you are interested. The cardboard items have names written on them, so I will black them out.
