Gold-colored metal keychain featuring the HYDRO logo. I received a few of these from acquaintances, but I don't know much about them. They appear to be quite old, so they may be rare. I couldn't find any information on Google, so I'm not sure about the appropriate price. - Brand: HYDRO - Color: Gold - Material: Metal - Design: Logo - Accessories: Original box There may be scratches or stains due to age, but it is, in principle, unused. There is something that looks like peeling on the inside, which is probably due to aging. Thank you for viewing.
