This is from when I was a breeder over 10 years ago. I was raising extreme stag beetles around the time Gordon R. beetles were circulating. I'm no longer using it, so I'm putting it up for sale. It hasn't been used for over 10 years and is considered junk. Those who know about these things, please consider. This is for one unit. I have two others, and I plan to list them if these sell. Please refrain from purchasing if you are nervous or seeking perfection. It hasn't been used for over 10 years, so it's in poor condition overall and is considered junk.
