Thank you very much for viewing. This is a GENTOS LED headlamp (HW-G533H), a proven product, of course, for its light. It is new, unused, and unopened. I also use it, and it has a brightness of 600 lumens, it's bright, and I can use both hands freely, which is very convenient. It's a great item for not only disaster prevention but also for walking, fishing, and work. The regular price is 6578 yen, so I think it's a great deal, how about it? Although it is unused, it has been stored at home, so please purchase it if you understand.
