This is a Hiyashi Mushi-ya HI. I purchased it several years ago and used it for insect breeding. Operation has been confirmed before shipping. Since it is a used item, there are tape marks etc. on the exterior. It comes with the instruction manual. Disassembly is difficult, so I will ship it without disassembling it. Shipping is included, so I would appreciate it if you could purchase it at this price. No claims and no returns, please.
