I purchased this new about a year ago. It is unused. I opened it for the first time when listing it, and checked the accessories and the movement of the main body's movable parts. The above were not a problem, but since it is unused, I don't know how it will function after installation. I will ship it in the original box. *It was in that condition when I purchased it. I am a non-smoker. I do not have any pets. I do not accept price negotiations. ・Reference: FlexiSpot official page "CH1" https://www.flexispot.jp/ch1.html I purchased this on Mercari a month ago with the above description. It didn't fit my PC, so I am selling it. I haven't used it at all since I bought it.
