For what it is, its well overpriced unfortunately. You get a few leds, some conductive thread, a battery, a battery holder and a paper instruction leaflet. These are all contained in a small cigarette packet sized tin.
To be honest, I liked the idea and wanted to see what the components were so I could buy them online cheaper. I've since done that and you can get the components a LOT cheaper. The other issue is that there are not a lot of leds in the kit (about 6 of the 3 colours) and this is very much a "taster" kit which has very limited practical use.
I'd honestly avoid this kit unless you're lazy, because a quick google will find alternatives that are better and cheaper.
