This is a Qrio Lock. Model number: Q-SL2 (Key) - Color: Black - Included items: > All items shown in the photos. I am selling this because it is not compatible with my new home. It has been used for a while, so I am offering it at a low price. Also, since this is a used item, please refrain from purchasing if you are overly concerned about its condition. ⚪︎Additional Information ・Regarding Use ① You will need to purchase batteries and prepare double-sided tape. ② The variety of thumbturn attachments is limited. If it does not fit your lock, I apologize, but please purchase one from the website. I believe it cost a little over 1,000 yen. Thank you for looking.
