The puzzle pieces stick very good, but the surface must be completely smooth. On our woodchip wallpaper, painted over with latex paint that was of course doomed in advance to failure. Our puzzle was stuck on a smooth plate. So we later have also not possible adhesive residue on the wall, if the puzzle not even like.
Lights do only the laser sword on the subject. Everything else is printed neatly and sharply.
Unfortunately, the pieces are very thin. The final image but it looks quite nice. For welded Star Wars fans the wall Puzzle is a great gift idea.
