【Product Description】 SONY Robot Programming Educational Material KOOV Advance Kit (Starter Kit + Expansion Parts) Model Number: EKV-200A This is a learning kit that enhances logical and creative thinking skills with numerous blocks and electronic parts. It's a robot and programming learning kit where you build shapes with blocks and give them movement through programming. I purchased this as educational material for my child, but unfortunately, my child wasn't interested and only used the blocks once. The parts other than the blocks are unused and have not been powered on. In preparation for listing, I re-checked the contents and confirmed that all the parts listed on the package are present in the correct quantities. Therefore, I cannot accept claims or refunds due to missing or insufficient parts. Also, the outer box has some tears (images attached), but the contents are in good condition. Similar to the policy regarding missing parts, please understand the condition of the box before purchasing.
