Gakken Electronic Block EX-150 I purchased this approximately 14-15 years ago and used it a couple of times before storing it away. Almost all of the accessories are unused and are complete as when purchased. I confirmed the operation by assembling circuits such as a radio, but I didn't test all the circuits, and the check was a simple one, so I'm selling it as junk. The outer box and the cover of the instruction manual show some discoloration due to age. The batteries in the image worked, but they are old and will not be included. I would appreciate it if those who enjoy this as a hobby would bid. Please refrain from bidding if you intend to resell it or negotiate a discount.
