STAEDTLER Lumocolor Permanent Refill Station 487 17-3 for Permanent Universal Pens - Blue

Quick, easy, and beats buying new markers when you can refill them a bunch of times from one refill container.

So easy to refill pens, and economical, too!

I like the color and pen style - great for its task.Got the refill as it seemed more economical than buying a new pen each time the blue F sized Lumocolor permanent ran out.Put the tip down in the well as the directions indicate, seating it fully, and let it sit there for several hours.Afterwards the pen wrote well. Put its normal cap back on, and put the pen back in the drawer. Some months later, pulling that pen out to use, and its almost dry again.So it could be the refill ink just doesn't go into the pen enought, so over time the fresh ink soaked up into the bigger pen storage and thus left the tip drier. Or the as the Lumocolor pens age maybe a crack or leak happens somewhere in the body that causes them to dry out over time.Result is disappointment. The pen is to unreliable using the refill station. I'll stick to buying new pens at I know can be left unused for months on end and be relied upon to write when called upon. (and yes, the cap is always solidly on the pen when its not in use).

USELESS. THE PENS DO NOT SUCK UP THE INK.
