The Uni Power Tank Pen...
May 24, 2015
The Uni Power Tank Pen and the Uni Power Tank Smart Series Pen have identical
ink cartridges. For some reason, unclear to me, the Power Tank refill and the
Power Tank Smart Series refill are not the same. The Smart Series refill
replaces the inner ink "tube" of the outer shell of the cartridge. This requires
quite a bit of manipulation. The end result, though, works just fine. The
Power Tank refill comes with the ink "tube" and outer shell together.
