Hi,. I haven't finished one of the cartridges yet, so it would be hard for me to tell you if possible. However upon simple inspection, I would say that it is doable, but there is a seal that might have to be broken or compromised to refill the tank, and that might affect how the Ink is released after (leakage). I believe though, that there is such a thing as refills for this markers. Hope that helps
