I received this item without its original packaging, so I'm unsure what it's for. Please refer to the images to determine its purpose. I lack product knowledge and haven't been able to confirm its functionality, so please consider it as a junk item. Only those who understand this should purchase. Please refrain from making claims or complaints after purchase. This item is available for immediate purchase. Price reductions are generally difficult as I will consider them myself. Please consider that this is a used item. To avoid any issues, please take a moment to read the profile section before purchasing the item. #carrozzeria #pioneer
