Ink refills for the ePen Pro (iCS810)
I purchased 3 3pack ( 9 cartridges ) refills in the past. I recently purchased three more 3packs ( and a new pen [ still using the first one ]). Writing with them only requires a light touch. I write a lot, where I work: the ePen makes it easier. Only drawback: they don't last forever. Redeeming quality: they are not expensive.
