A bootleg flexi label, believed to originate in Poland, or possibly in Russia, in Kaliningrad or Saint Petersburg. All releases are unofficial, and are mainly available through Polish record sellers. The name буд кон (sometimes printed as one word: будкон) translates to BUD KON, but this has no meaning in Russian or Polish.

буд кон has released hundreds of releases by various bands, since at least the 1990s, and possibly the 1980s. All releases are flexis, square-shaped 14 cm × 14 cm (5.5" × 5.5"), and released in various colours: transparent, red, green, yellow, blue, and brown. At least three variations of each release (one transparent and two coloured versions, sometimes three coloured) are issued. The sleeves are black and white computer printouts, usually highly pixelated, with random images that have nothing to do with the band or their music. The thin paper sleeve wraps around the flexi about a third of the way up the back, held in a thin plastic envelope.
