'Siwen Wave' is undoubtedly the most explicit board set that Caffeine Critical Imports. There are 5 envelopes in each box, and a few different "series" of artworks you have a chance for in each envelope. The "SEX Series" is the most explicit one.
Really nice, artwork was great quality but for that price you would expect to get a little better artworks than what you get. Overall pretty good, just not worth the price.
