Chrome plated steel 8 run for small animals, pulls apart and stores flat. By removing sections you can make it smaller or larger but as shown in picture it is about 95cm diameter. It is 25cm high.

Also one exercise ball.
I also have a large gerbil / hamster cage but there is a crack in the base. We held it together with duct tape for years, but a less lazy person could easily araldite it. 67cm x 37cm x 52cm
Also a bag of sawdust and a bag of hay and some gerbil food.
Collect from near Hartley Wintney or Woking
