I found this while cleaning my house (^-^). I don't know how to use it. The battery compartment looks rusty, so I haven't confirmed if it works. Therefore, it's being sold as a junk item. Please check the photos before purchasing. Great for parts, etc. (^-^) Please refrain from purchasing if you are looking for a perfect item, as it is a home-stored, junk item m(_ _)m Please understand that this is a junk item and is sold as-is, with no returns, refunds, or exchanges.
