Octagonal metal playpen for small animals, providing ample space. - Model Name: Small Animal Play Pen - Shape: Octagonal - Size: Ample space - Material: Metal - Application: For small animals Thank you for viewing. I accidentally deleted the listing and am reposting it. I apologize to those who liked it. This is a Marshall-made circle, a representative ferret farm. It's easy to use with a grid spacing that makes it easy to attach water bottles, etc. I mostly let my ferret play with it when I was at home, but I thought it might be stressful to be confined to the cage when I wasn't there, so I bought it to connect to the cage and make a play area. Due to the product's construction, the paint on the connecting and moving parts will inevitably peel off after a few uses, but this does not affect its use at all. I have also cleaned it. The last photo shows the back. Size: Height 740mm x Width 460mm, set of 8 panels Steel spacing 20mm
