I find this very beautiful enclosure. My Meeris have in there enough space in there. The package arrived in 2 large and a small paketeen with screws, dowels in it.
To assemble you need 2 people, alone, it turns out to be difficult.
The ground you have to still make urine sealing. I took eg pond liner but it would go even PVC.
I am very satisfied and can only recommend the enclosure. :)
