My favourite pen has been discontinued, and that has truly destroyed my soul - however, it is an opportunity for me to lower the amount of plastic waste I generate in this world, as I go through a LOT of pens, so... Who has pen recommendations?

I& #39;m a black ink roller guy - I prefer the rich black you get with gel ink, and the ease of writing.

Ideally I& #39;d find someone who sells the internal gel cartridges and refill an outer pen "case" kind of thing, if you catch my drift. It& #39;s not perfect but it& #39;s still less waste.

Will happily receive recommendations for both the black gel ink refills and the outer cases.

For those expecting me to be a fancy pen purist, please, behold, my favourite pen.

(I am however very snooty when it comes to biros. I cannot and will not use them unless I absolutely have to write on something shiny)
