I have something like that Mike. To be honest, I think the box is too big for pens, and the light gets lost. I think I like the pictures of my pens taken inside the white trash can the best so far.
I made one that is about 15"x15"x20" out of PVC and a white sheet for around $6.00. I didn't glue the joints together, so it can break down and store easily. IMHO, you'd be better off making your own.
