Dwarf suitable play pens

[Taze1992]

Hi everyone,
I've had my Bashful for a while now, hes a Chinese, and he prefers to clamber all over the place and run free rather than a ball.
I have seen playpens but they seem to have large bar spacing, so are there any suitable for a dwarf hamster?
It doesn't need to be large but 2 meters or so worth of space would be good, I would prefer one which I could attach ladders and such too.
Are there any out there or could anyone suggest a DIY which isnt too lengthy or hard to achieve!

Thank you

I wouldn't use the barred ones as I have seen dwarfs get their heads stuck through these.
There are some pens stickied at the top of the DIY section on how to make cardboard or correx ones which are held with clips and very easy to make. You could adapt cardboard or hardboard for these.
