Thank you for viewing! This is a large volume set of Kumon Publishing's Kumikumi Slope. It's a large set because I've purchased additional sets, allowing you to combine the mechanisms to create large courses. - NEW Kumikumi Slope - Volume Up Set - Jump & Ferris Wheel Set This set is composed of these, but there are some missing parts, and everything in the first photo is included. There are 14 plastic balls. Please check photos 11-13 for parts with noticeable dirt, cracks, or breaks. Please understand that due to amateur inspection, there may be cracks or breaks other than those in the photos. There is one instruction book for the NEW Kumikumi Slope. There is some tearing, but it is still readable (photo 13). It will be shipped in a recycled cardboard box. The balls are bundled in a capsule (photo 10). Please purchase if you understand that this is a used item that has been used by a child and stored by an amateur. Please refrain from purchasing if you are sensitive to these factors.
