This pack contains 5 RAW tubes. The tubes are not cleaned up and they do have a backgound which needs to be removed. Thus, for usage they need some work. But that is why the price is so low.
I make a lot of tubes and throw away a lot to! So i figured, maybe some other designers (or just others who like to do this) like them for usage.
The images are 2048 x 2048. U can use them as CU or PU.
