This is an aluminum earphone case, the type that comes with custom IEMs. This is likely a promotional item, as it doesn't have a model name engraved on it, which in a way makes it easier to use. The condition is generally good, as it has been stored unused since I obtained it. Please forgive any age-related deterioration or scratches, as it is an old item. This is an auction for the case only. Please understand that I cannot answer inquiries regarding the period of use or frequency of use, as the items I am selling include used items. Shipping is included, and the item is a bargain, so please refrain from price negotiations. Immediate purchase is welcome!
