Refills will be available from Jan 1st 2015 (in about 75 days) 

The inks last a LONG time! .. many of our testers have been using the pens for 6 months and doing a LOT of coloring 

so you should not need to refill the inks for at least a few months 

The mixing chamber is also refillable but because there is a mixing chamber for each of the 20 colors it takes a long time 

to run through that as well. 

We will have videos showing how to refill both pens and mixing chamber on our site shortly and the refills will be avail Jan 1st
