I do have 2 pens. I actually got both of them at yard sales for $5 each
I found that usually it is cheaper to buy baby pens. You can buy them at Walmarts and such in the baby department and are cheaper then dog pens.
The ones I got are the nice molded white plastic that fold up like a sandwich style instead of accordion style and you can just click open and shut and conform to all kinds of shapes like L shape or octogon or rectangle, which is nice for fitting in odd spaces |
