Fisher Space Pen Medium Point Refill, Blue

The refill is excellent it works perfectly on a cross pen as described; however the drawback is that it becomes quite light and pressure has to be Placed while Writing. It would be great if the ink was dark blue and Furthermore, if the refill would come in different colours it would be perfect and very helpful.

FUNCIONA EXCELENTE

I use the at work on construction sites. They are the best imo.

I love Fisher Space Pen cartridges. It is great to be able to have the always writing Space Pen cartridge in a quality Cross pen. I chose the Cross Century II. This cartridge fits perfectly in the Cross Century II ball point pen. It does not fit the Cross Century II rolling ball pen. If Space Pen ever makes a gel rolling ball cartridge for the Cross Century II Selectip rolling ball pen, I would buy that cartridge too. Until then, make sure you are using a Cross ball point pen, not the rolling ball pen.

My bad I bought this for the space pen but its totally not for the space pen. If I had been paying attention the label by fisher space pen was not really what it is. I take responsibility but dang thats some goofy packaging -

I've used Fisher refills in a variety of pens for years. They write very smooth, last long and write on anything. Much better than the Cross refills, however I really like the Cross classic design.
