I used this item only a few times after purchasing it new, but I'm selling it because I no longer need it at my new place. There is some minor soiling on the top of the main unit. The window panel has tape marks, etc. It will be shipped as shown in the photos. Please note that the only spare tape available is what was originally included with the unit. There are also some scratches, so please refrain from purchasing if you are concerned about these. It has insect prevention features, so you can use it with peace of mind. I have lost the instruction manual for the main unit, so please refer to the website. I believe the main unit is almost unused, but please purchase only if you are not overly concerned about its condition. Shipping will be via Kuroneko Yamato in multiple packages.
