Super simple to refill and swap out. Glad I got some so I can switch tips or colors easily.

Love the whole concept of Lumos, have got several now. It's nice to ink up the reservoir and use it ... for days ... ran out of things to write before the ink gave out. .left it for a week, still writes beautifully with same fill from the week before ... yes even in this dry weather, surprised me. it's a 5* from me i love the pen, the nbs the reservoirs, the whole shebang ... now for some more inks to go in my reservoir storage.


It’ s very convenient if you have different colors of ink are ready for use at any given time

Great pens and a range of spares and accessories to keep them running. Perfect.
