Unfortunately, I have only just discovered Aqua Doodle where my kids (5 + 2) already partially painting with proper pins or want ... But traveling in the car or at the doctor, it is super convenient !!! The child has his little bag about to water to fill the pen you get almost anywhere and there is nothing verkleckert and spilled !!! The Painted disappears after about 4 minutes. again and again it is space for new things !!! In retrospect, I would recommend the Travel Set for Mala catcher from 12 months - comes naturally to the child !!! It may uncontrollably start painting without equal sofa or table to ruin !!! However, I would use the pen only under supervision, which must indeed screwed to fill in the other direction are the little but get out quickly and take the items possibly into the mouth. For me, this is clearly a must for every creative toddler, as rather I wipe three drops of water away (if it because times but the lid unscrews!) As a marker pen stains !!!!
