Fantastic to be able to make your own colours - I've mixed a few variations in these empty pens and use them all of the time. Great product!
Have started to do more drawings on whiteboards so wanted to be able to use the larger pens with the whiteboard ink. This was not a standard option, but with this empty pens I made myself a set and they work really well and provide that ability to line and support the use of the Bikablo approach on a whiteboard.
