This is a rare, new, unopened Gogo Brace. The box has some minor stains, but it is an unopened item and is now difficult to obtain. I purchased this deadstock item and stored it in a dark place as part of my collection. Since it is unopened, I have not been able to confirm its functionality. This toy was released in 1999, and I cannot be held responsible for any defects, such as it not working. I would appreciate it if you would consider purchasing it only if you understand and accept this. The price reflects its rarity.
