Brand new but slightly imperfect cold frame on stand

I have a cold frame on a stand which is not being used. I got two but in the end a only using one of them. Product page from where I purchased is at https://amzn.eu/d/0d8bRMo/. The clear panels are some sort of plastic/perspex.

To be honest, they're not the best quality frames. Both had similar sorts of imperfections, but despite them, the one I'm using seems to have gone together well enough for its purpose. Below are photos of the most obvious imperfections. 

I wouldn't pay the £60 I paid the Amazon trader again, but I would pay £20 which is what I'm offering this one for. It's good for overwintering things like pelargoniums and starting seeds a bit bit early, if you're that way inclined. Warning. it needs to be assembled - a bit of a pain, but straightforward enough.
