Dreamed up by nine-year-old Greyson MacLean, BrickStix are restickable cling decals that are revolutionising building block play. Fill your plastic block space ship with aliens, put a dent in a ute – and change them as often as you like. There are six cool themes, including Space, Transport and Shops and the decals work with most smooth plastic blocks, including Lego.
