How to Maintain your felt tip.

For an optimal care of your Yookers pen !

Our system uses water based inks, from times to times, water may evaporate and leave your tip blocked, this is a normal phenomenon and  not the end of your pen, we strongly recommend you to read the care notice that should allow you to fix your possibles issues …..

Oh, and if you are in a hurry, substitute  the lukewarm water suggested  in the notice with a hot one, this will not harm the tip… 😉
