Great for my enthusiastic doodlers. My agenda is also to improve clarity in handwriting and break out from over detailed intensive doodles. Gives a good and easy way to make mistakes and have them vanish - no fault art! I have seen my teenagers produce some amazing drawings (which have then vanished of course - perfect tool!)
Easy, simply, no mess, no refills, no moving parts, profound, creative, mind-expanding - truly a buddha product.
