Several of our customers have requested this water-based marker that's included when you for example buy a Svenpad Picasso.

This looks like its drawn by a sharpie, but the sharpie is water-based and does not go through the paper. It is therefore perfectly suited for use in conjunction with Svenpads and other trick where you do not want the line to be clearly visible on the other side of the paper.

The price is for one piece.
