・ This is the Gakken Electronic Block EX-150 reproduction. ・ The outer box has some damage, the instruction manual has folds and stains, and page 6 is partially detached (images 7, 8, and 9), but the main unit appears to be clean and without scratches. ・ All accessories are included (image 5). ・ In preparation for listing, I created some circuits (No. 075 Electronic Horn, etc.) and confirmed that they work, but I have not checked the operation of all electronic components. ・ Please consider this item only if you understand that it is a used item, and no claims will be accepted.
