Branching out…

The spare ink reservoirs mean that I have more colors loaded and ready to use…so much better than finding/wasting another disposable pen!! Thanks Tom! so many inks..so little contribution to the worlds waste disposal issues!!

Clean and easy to fill.

The refill reservoirs are clean and easy to use. That’s on the second and subsequent fills when for my own tendency to get covered in ink, I decided to use tweezers to hold the reservoir and return it to the pens.
