I found two old pens in a drawer and of course the refills had dried up. It took me a while to find these but they are perfect for the pens and I now will know where to buy more. This retailer does so many other type of refills, if you are finding it hard to get the ones you need, please try this retailer.
And love the refills. Smooth flow and easy to use. No pressure required which is great as I have arthritic hands. Would definately buy them again though probably won't need to for some time as they do last very well.
