I have 4 x medium and 4 x small mice / small animal boxes which I can sell because these are the ones I started with and I've changed to different types. Both types stack on top of each other they're the same as the ones here

So they have clip on lids which open both ends. The "medium" boxes are 35litre and the "small" ones are 12litre they all have meshed lids, a side "window" and an end "window" £8 each for the medium ones and £4 each for the smaller ones I'm in Kent
Will take pictures in a minute
