【Extremely Rare】BANDAI DIGIROBO AQUABOY Robot Watch Battery replaced, operation confirmed. Transformation also works perfectly. Includes the main body and instruction manual. A fully functional Aquaboy is considered very rare. Moreover, it comes with the instruction manual. It seems to be part of the DIGIROBO TOKIMA series released at the time, but this particular model seems to have had a limited release. It appears to have a waterproof function, but the packing is likely deteriorated by now, so please do not put it in water. The condition is not bad considering it's a vintage item.
