so this is a little bit awesome - it amused us for far longer than it probably should have! boys and girls will be amazed at what they can create with this awesome art set including x3 tri-markers, x20 drawing paper, x1 3d paper glasses. to use, kids (or bored grown-ups) draw their own design and watch it come to life through the 3d glasses. magic! the hamleys 3d tri colour markers is suitable for children aged 3 years and over.
