Thank you for viewing. I purchased this in April, but I haven't had many opportunities to use it, so I'm putting it up for sale. I've only used it two or three times. (During that time, it was kept indoors, not in a box.) I am a non-smoker, and I don't have any pets. I've lost the instruction manual, so I apologize, but please refer to the online manual (it was a very simple, few-page document). The outer box is included, but I'm sorry, I will ship it as is, without further cardboard packaging on top of the outer box, so please be aware of that. I won't be making any significant price reductions, but I will be lowering the price by 500 yen each day from now on, so it's first come, first served. Thank you very much.
