This is a foldable and detachable metal dog crate with a door and lock. I used it when my puppy was young for when I was away, but I'm selling it now since it's not used much anymore that he's an adult. There is no bottom tray. It will be disassembled for shipping, so you will need to assemble it yourself (no tools required). ■ Size Width 55cm Depth 39cm Height 40cm
