A whole book in one file. Rather than choosing pages one at a time, these are complete coloring books as a single PDF — like the Alice in Wonderland edition with 25 whimsical illustrations of Wonderland's cast.
Print the pages you want, as many times as you want, on the paper you actually like. That's the quiet advantage over a printed book: if a page goes wrong, or you want to try the same illustration in a different palette, you simply print it again.
The download arrives the moment payment clears. No shipping, no waiting, no customs.
