The series contain pro CD-R metal releases issued in Russia in 2001-2005 or so. There are replicas of original CDs as well as replicas of pirate CDs (e.g. Спюрк) and out of print licensed CDs (e.g. Irond). Mostly there are colour-printed 4-page booklet (pages 2&3 are blank) and single-sided inlay. CD-R has black print over silver (or sometimes white) surface. Their pricelists were also known as KR or, afterwards, KROMA. The same label, at a later stage, switched to replicating (pirating) some original releases as factory-pressed CDs with full-color artwork, and multi-paged booklets.
