This is a set from when I was keeping stag beetles. The oak mat is quite low, so I think you should purchase more. ■ Breeding case: The large window is ideal for observation. There are some scratches, but it's still usable. Approximate size is 40 cm wide, 21 cm deep, and 19 cm high. ■ Amino Jelly 37 pieces remaining, opened. Expiration date is November 2027. ■ Anti-mite King (Hinoki Mat) It's good to mix it with the oak mat to prevent mites. Also, when insects get mites, putting them in this 100% hinoki mat for a few days will remove the mites. ■ Fruit fly repellent sheet Place it between the lid and the body of the insect case. Opened, but there are two sheets of 52.5 cm x 35 cm. ■ Square or Anti-mite Zeolite Can be mixed with the oak mat. Please see the photo for the remaining amount. ■ Anti-mite spray This has also only been used a few pumps. All items have been opened, but they are still usable, so I am selling them. Please purchase with understanding. Thank you.
