This is an aroma diffuser from Sogo Matsushima's "Ko-ten" exhibition. I purchased it at the exhibition venue. It is new and unused, but I opened the box once to check the contents. As a bonus, I will include a letter I received at the venue. I am also selling a white ballpoint pen and a black ballpoint pen, so if you would like to purchase them together, please let me know in the comments.
