Recarga de Esferográfica Preta Easy Flow 9000 3 un.

The ink flows so effortlessly that my handwriting actually looks neater, which is saying a lot. I’ve been using the same refill for weeks and it hasn’t skipped once, and the fit in my pen was perfect right out of the package. These three are going to last me a good while.

Finally, a refill that makes my Retro 51 feel brand new again—the smoothness is night and day compared to the stock one. I've been using it daily for two weeks and not a single skip or blob, plus the black is deep and crisp. Three in a pack means I'm set for months.

The ink flow is so buttery that my handwriting actually looks neater now, and the black is deep and rich on cheap office paper. I've already gone through two of the three refills in my favorite rollerball, which says something about how much I've been writing.
