Bornelund 100 Bead Abacus Wooden A large abacus that helps children recognize numbers from 1 to 100. The horizontal abacus allows all the beads to be seen when moved, making it perfect for children who are just starting to count. It is characterized by different colors every 5 and 50, making it easy to recognize numbers. I've never seen it for sale anywhere, and I bought it used 5 years ago after searching for it. This item has been used by a child, so please understand. It does not have a box, so it will be packed and shipped.
