When unicorns travel: The small purple trolley by Ylvi has an XXL unicorn motif on the front on a cheerful, colourful, collage-like background made of satin fabric. Super cool: The wheels of the trolley light up colourfully when they turn. With pull-out telescopic rod and two zipped compartments. Without batteries: The LED wheels produce their own energy by means of a magnetic core that generates electricity when they move.
