(Additional Note) I apologize, but I will be unavailable to ship from the 27th to the 29th. This is a set of two SwitchBot Locks (black). They are in good working condition, but one of them is missing the mounting sticker. (The other one has its mounting sticker.) You can still use them without issue if you provide your own sticker or magnetic installation kit. (Generic ones like 3M are available for around 300 yen.) One of them has a small scratch (see photo 6), but it's not very noticeable and doesn't affect the operation. Therefore, I'm offering them at a bargain price. (Effectively 3350 yen per lock, including shipping) The edge of the protective sticker on the knob in photo 2 is slightly torn, but I've left it as is. There are no scratches on the main body. Other included accessories are as follows: Phillips head screwdriver, SwitchBot tag, thumb turn adapter, magnet, instruction manual, spare screws, label sticker It was very convenient to be able to lock and unlock the door and see the status via the smartphone app. If your home entrance has a twin lock, you can link the two locks for opening and closing. I am selling them because I switched to a different model. (This is a set of two. Individual sales are not possible.) The surfaces have been lightly cleaned and disinfected. Other than the above, there are no visible scratches or stains. (No pets or smoking.) Although they are in good condition, please be aware that they are used items. Please feel free to contact me if you have any other questions. Thank you.
