Many photographers might not have a setup. including lights suitable for closeup photography. They also might not have the space to store one nor the financial ability to purchase the needed lights.
I found a light tent for closeup photography on eBay that takes up virtually no space either setup or folded for storage and it is pretty well dirt cheap at a little over nine U.S. Dollars. It also does a pretty fair job in lighting small items - such as lenses - for sale on eBay...

I keep it folded in my file drawer...
It comes in its own drawstring storage pouch...
It is easy and fast to setup and takes minimal space on my desk - power is from a USB cord...
It comes with various colored backgrounds but, I could use colored craft paper as a BG...
Great size for small subjects like lenses...
Its performance is quite reasonable considering the price...
I have other lighting setups which can probably do a better job. However, I am frequently in need of shooting small objects and this unit is a quick and satisfactory solution...
