Thank you for viewing. This is a TROIKA airplane-shaped key holder/keyring. It's from the LIGHT FLIGHT series and made of metal. I bought it a few years ago for around 3000 yen, but I haven't had much opportunity to use it, so I've been storing it. When you press the cockpit part, the blue LED at the tip lights up. The battery life is nearing its end, and the light is dim, so I recommend replacing the battery if you intend to use it as a light. (It uses a common button battery) I'm offering it at a low price, so I would appreciate it if you could understand that it is a used item before purchasing. - Brand: TROIKA - Model Name: LIGHT FLIGHT KR99-44 - Design: Airplane-shaped - Material: Metal - Accessories: Box, Instruction manual Thank you for viewing.
