this Filzstife come super with my daughter on (19m). Without much effort you can now paint the most beautiful and colorful minutely art. If something goes wrong, it can be easily abwachen, whether wool, skin or wood (walls, we have thankfully not tried!) Unlike chalks the colors are more brilliant even without hard or scrub (which, however, also no harm to the felt-tip-top leaves). The only "problem" are the caps, which they can not deduct alone.
