This is a used Hiyashi Mushiya DX. The outer case is an older type, purchased used. However, the cooling and heating unit was purchased new from Sealer Case in August 2021 and has only been used for about a year, so it's in perfect working order. The DX model has a larger capacity than the currently sold HI series. I am selling it because I am no longer keeping stag beetles and it has been sitting in storage. Outer dimensions: Width 80cm x Height 60cm x Depth 45cm Inner dimensions: Width 63-65cm x Height 47-48.5cm x Depth 36cm Temperature settings: 1°C to 40°C, Peltier type cooling and heating As mentioned in the manufacturer's description, the set temperature may not be reached if the difference from the outside temperature is more than 10 degrees. I did not receive a warranty when I purchased the cooling and heating unit, so I cannot provide any warranty information in case of a malfunction. Currently, it is working without any problems. The outer case has discoloration, small scratches, and scuffs. The left door is slightly sagging. Please check the photos. Only the items shown in the photos are included. Please refrain from purchasing if you are concerned about it being a used item.
