【Product Description】 Logitech's popular trackball mouse, the **M575SPd ERGO (Japanese Domestic Genuine Product)**. Purchased new on December 25, 2025, from the Logitech official store for 7,240 yen. Used for approximately 1 hour only, and is in almost unused condition. Operation has been confirmed, with silent clicking and connectivity working without issue. I tried using a trackball, but it didn't quite suit me, so I'm selling it while it's still in good condition. 【Product Condition】 ・Usage time: Approximately 1 hour ・No noticeable scratches or stains ・Purchased from the Logitech official store on Yahoo Shopping ・Japanese Domestic Genuine Product 【Product Features】 ・Trackball design for space-saving ・ERGO design for wrist comfort ・Silent click ・Bluetooth / Logi Bolt compatible ・Windows / Mac / iPad OS / Chrome OS compatible 【Model Number】 M575SPd 【Details】 Please check the attached photos for details on the product condition and included accessories. 【Notes】 This is a used item, so please refrain from purchasing if you are concerned about minor details.
