Thank you for viewing. I used this once to obtain a certification. There are some stains, but I think it's fine for use. Price reduction is OK. - Please refrain from purchasing if you are nervous about the condition. - Please look at the photos carefully before purchasing. - Immediate purchase is welcome. - Basically, I will ship the item the next day after purchase, but it may be delayed due to work circumstances. - I will not lower the price myself, so feel free to comment with a price reduction request. - I don't smoke. - I have a cat. Please be aware that there is a possibility of cat hair getting in.
