The CDs are professionally duplicated+printed. They are thermal printed (with photo-finish) and come in thick cardstock CD jackets that are shrink wrapped.
For those curious about previous editions since this is volume 4, it's cumulative and includes everything that was on older versions.
Uploader Note: When I bought this CD, I was quite disappointed to see she simply downloaded many of these images from her FA and slapped it on the CD. Also many of these images are TINY tiny. Like FA tiny. But these are the original files from the CD directly.
Some of the files are TIFFs and PSDs so make sure to pull down the torrent to make sure to get everything.
