The term flim-flam means: A deception, a swindle.
This puzzle is exactly that: A swindle. It pretends to be a puzzle with special new moving abilities although it is "just" a 2x2x4 shape modification. These pieces are designed to be glued onto a Rubik's brand 2x2x4 puzzle. The stickers can be bought from Oliver's Stickers here.
