The digipak was made to resemble a vinyl with the cardboard covers but instead of holding a vinyl it holds a CD.
The good thing about digipaks rather than a CD cover or a Vinyl is that it is smaller in size than the vinyl but lighter in weight then a CD this makes transport cheaper and will also mean that shops can hold more inventory of digipak.
Digipaks have become very popular, due to the artwork they appeal to collectors, because of the paper feel it targets the nostalgic fell of vinyl. Because of its popularity it has a target audience on youtube of unboxing videos.
On one page you can see the main cover which has the title of the title of the cover. On another page you can see a list of the songs that are on the CD. On the last page that we can see you have a medium close up of the artist.
Depending on the digipak whats on the pages might change. Some have a bunch of text but the most common is photos of the band or artist.
Bring Me The Horizon do have a digipak for their album "THAT'S THE SPIRIT". I found an unboxing video for the digipak and their box set (the video is in Spanish and the unboxing doesn't start until 2:35). It is very simple with no photos used only a black background with either white font or a different colour black. On the back there is a list of the songs, a barcode, music label, parental advisory warning and trademark message. The inside of the pack has one painting which goes over both pages with bright colours. The disk is in-between the paper and you have to grab it by the top to get it or you have to slide it out. There is also a booklet with some information on.
