116 Fountain Pen Ink Cartridges 3.4 mm refills (Harlington UB3)

I have a large quantity (116) of 3.4 mm cartridge pen ink refills, a mixture of black and blue refills. They have been sitting in a drawer for some years, so some may have dried out, but imagine that a good many, if not all, will still be usable. Collection from Harlington, near Heathrow. Please let me know possible days/times when you can collect in your reply, thank you.
