Query: Great product

I always use Staedler for my zentangle. Someone recommended the Sakura pen. It was a great experience. I used it on different kind of paper and it absorb it very well. Still I do not like to use it on surface such as domino cause it I have to pass the pen several times and it takes for ever to dry. but besides that the pen are fabulous!
