I miss my Pentel Tetra Rollerball (non-refillable) Pens  {why, o why did every store I shop at quit selling them????)}.  And I know I will never love like that again, but meanwhile, I do believe in a free-flowing ink.  These were at the bottom of my bag during a recent cleaning/re-org.  All beautiful in their own way.  All very fluid, some gel, some marker.  Just not my smooth, glaze-a-licious rollerball.  Not my Tetra.  *sigh…

Inks in purple, blue, black, green, even red.  They try.  They do so try…
