I have two 20 gallon terrariums w/locking screen tops for sale. One of the screen tops does have a quarter sized hole in it, and the other is still intact. The one with the still intact screen top is $25, whereas the one with the hole in the screen top i am selling for $20. If the hole in the screen top does not affect whatever you are using the cage for then that's good news for you, but i am still selling the perfectly fine tank for at least a dollar a gallon. If you are interested you can text me at
