Thank you for viewing. This is the Logicool ERGO M575 Wireless Trackball (Black). I only tried it a few times after purchasing it, and it has been stored in its box almost unused. I am selling it because it didn't quite fit my hand. Operation has been confirmed, and there are no particular problems. I don't see any scratches or stains, and I think it's in overall pretty clean condition. (Please check the photos for the condition) The outer box has some scratches. The instruction manual is missing and will not be included. ■ Main Specifications ・Connection: Bluetooth / USB receiver (Unifying) ・AA battery x 1 ・Right-handed ergonomics design ・Color: Black ■ Included Items ・Mouse body ・USB receiver ・AA battery (installed) ・Original box ■ Purchase Date Around 2024 Stored in a non-smoking, pet-free environment. It will be carefully protected with bubble wrap, and shipped via anonymous delivery (Rakuraku Mercari Bin) within 1-2 days. The price is set based on the market price, so significant price reductions are difficult, but please feel free to ask if you have any questions. I will do my best to ensure a pleasant transaction until the end, so thank you for your cooperation. #Logicool #Logitech #M575 #Trackball
