Thank you for viewing! This is a smartphone holder for the rear seat, designed to attach to the headrest. I personally use this rear seat smartphone holder. I think there aren't many rear seat smartphone holder products available, but this one is incredibly convenient, and I think the headrest attachment is a clever design. It can hold smartphones and tablets, of course, but it can also secure a Nintendo Switch, making it perfect for kids to play games in the car. The arm is adjustable, so you can move it freely to your preferred viewing position, bring it closer, or fold it compactly to avoid obstruction. There's also a hole for inserting a charging cable, allowing you to use it while charging. Installation is super easy; it simply clamps onto the left and right insertion shafts of the headrest, and you're done. I personally insert a thin rubber sheet into the metal part of the headrest insertion shaft to minimize any wobbling. *To offer it at a lower price, I plan to disassemble the arm and ship it compactly via Yu-Packet. *If you prefer to have it shipped assembled, we can ship via Takkyubin (courier), Yu-Packet Plus, or Letter Pack Plus. In any of these cases, it will be an additional 400 yen, so please comment before purchasing. *After purchase, we can only accommodate shipping via cash-on-delivery Takkyubin (courier). *Although it is new and unused, there may be some minor scratches due to being an imported product. Please understand this beforehand. *The color and shape may slightly differ from the photos depending on the production lot, but the basic specifications are the same, so please understand. ★About Shipping★ ・Shipped from Hyogo Prefecture. ・Generally, it will be shipped within 1-3 days after payment confirmation, but it may vary depending on the timing. *Please contact us if you are in a hurry, as shipping may be significantly delayed due to outings, etc. Please bid with the above in mind.
