Not expensive and they work

If like me you want to use your own ink this is the way you should go- easy to fill and the little view finder allows you to see how much ink remains at any time. It does its job- easy peasy.

It's smaller than others I have for my other pen. It also stops it's ink flow from time to time causing me to have to take the pen apart and manually push the ink down to get it to flow again. Other than that, it holds ink just like it is supposed to.

Got the accessories as part of the main gift for my brother!
