This is sold as "PRISMA PHOTO LIGHT BOX"
Bought this off of our local "Info-Mall" (something like Kijiji) from a man in the next town who had bought it when his wife was into making and selling jewelry. Said he used it for about a year, then she stopped making jewelry.
it is pretty solid. It is not made of fabric but some sort of opaque plexiglass. Seems to be only sold on eBay. It is marked as "Made in Canada" and the eBay.ca shows it coming from Toronto and made by Fit Studio. Can't seem to find anything else out about them.

Anyway, it works, it's solid and got a heck of a deal.
Just tried a could of objects to see how it goes (too lazy to dig out the tripod so these are hand held shots.

My other hobby - model railways. This is "N" scale (wheels are 9mm wide, hence the "N").
And had this sitting on my workshop desk so decided to shoot it.
I just grabbed my D90 and the 105 Macro - because they happened to be handy. Did I mention feeling lazy tonight.
