This is a set including a bug cage, substrate for beetles and stag beetles, jelly, food dish, leaves, and activated carbon for odor removal. The bug cage size is approximately 30.5cm wide x 16.5cm deep x 18cm high (with the lid on). It has been used, so there are scuffs and small scratches on the corners. The jelly has been opened, but there are 4 pieces remaining. There are also remaining leaves. The substrate was purchased this spring. The activated carbon for odor removal was also opened this year and has some remaining. The food dish is from after the jelly was eaten. If you've just received beetles, stag beetles, or larvae and have nothing at home... with just this set, you should be able to get by until you can get new supplies.
