This item was used when I was in the first grade of elementary school, so it shows its age and has a corresponding level of wear and tear. There are a total of 40 blocks. The paper calculation sticks are 20 bundles of 10 + 4 bundles of 5. (Some are bent.) The case has scratches and stains. My name is written on the counting chips. This is a very useful tool, so would anyone who needs it like to have it?
