Well, one French yogurt pot of pens and two treacle/syrup tins plus an olive and a baking powder tin of them.
A few years ago, I couldn’t walk past a stationer’s or an art store without going in to see if they had an interesting pen for me to try. Today I’m happy with my TWSBI Eco T fountain pen so I stick with that, which probably is Eco-friendly, as – locally for us – all those single-use pens can’t go in the regular recycling and apparently end up in an incinerator, although Douglas Adams put forward the theory that missing ballpoint pens slip through a wormhole into an alternative dimension.
As usual, I’m using Noodler’s waterproof ink and Winsor & Newton watercolours.
