The Russian label Budkon (BYA KOH) published between 1989 and 2001 a flexidisc collection for almost every track of Queen and Freddie Mercury solo production, not only songs originally released as singles. The flexis, that are extremely thin and light, have been made without any permission or license, therefore these kinds of objects are labelled as bootlegs, even if they got a certain popularity between collectors. Not only Queen have been published with this label, but many western artists share this kind of unofficial press.

Their size is 6 by 6 inches square (so a little bit smaller than regular single vinyls); only Bohemian Rhapsody was issued as a regular 7 by 7 inches. Each release has been published in several different colour variants and these flexis were housed in black and white picture covers, with a low-resolution laser printed image used as envelope and a unique catalogue number printed on the back. In some songs the picture sleeve chosen is the same with only the title different.

Sometimes the songs are not spelled correctly (or the wrong artist is credited), and in some examples they are not even recorded complete. They all have one playable side only and the sound quality is very poor due to the thin and plastic material used, not comparable to a standard vinyl press.

The following records are in alphabetical order.
