The Maxi Magic fibrepens by Milan are unique and fun. This pack contains 8 coloured fibrepens and 2 ‘magical revealers’. Use the fibrepens to colour, wait 5 seconds and then enjoy changing the colours into new ones with the magic revealers. You can also write secret messages with the magical revealer and simply colour over it with the coloured fibrepens to read the message. The Maxi Magic pens have strong and resistant tips that can be used to create lines from 1mm to 3,25mm thick. The ink used is water-based.
