Educational toy for learning numbers using 120 beads. - Brand: KUMON - Product Name: Kumon's Bead Abacus 120 - Target Age: 3 years and up - Features: Expands the world of numbers with 120 beads - Colors: Red and Blue Thank you for viewing. I purchased this a year ago for my child entering first grade, but they didn't use it much, so it's in good condition. The bottom edge of the first sheet is slightly curled. Please refer to the photo. The second sheet has never been taken out of the bag. The instruction manual is missing. I will include it if I find it. Would anyone interested like to purchase it?
