Lego Friends rollercoaster set 41685. Missing approx 5-8 individual pieces, but otherwise complete and great fun to play with. Some of the parts of the roller coaster are glow in the dark and so will light up in the evening which is very cool. It comes with all the instructions and is currently assembled although will have to be disassembled somewhat for posting. Would make a fantastic addition to a current collection of lego friends but also is a big enough set to stand on its own.
