Lanxivi Set of 3 Piston Vacuum Fountain Pens with Extra Fine Nib - 013 Series (Blue, Green, Clear Transparent) by Paili - Perfect for Calligraphy, Journaling & Office Writing

You can't really be unhappy with vacuum- filler pens that are smooth to write with, have little to no feedback, have a large ink capacity and are decent quality for a great price... and you get 3 for a third of the price of other more expensive pens.You will need to grease the piston rod though before use just to give the pens a better chance of fighting any rust. I haven't seen any indication of rust as of yet but I did pull out the rod of each and coat thinly with silicone grease for better performance and water resistance.If you see negative reviews really consider that this pen is a partial clone of another pen that costs upwards of $65. You get three similar pens, with just a reliable a mechanism and ink capacity for $20. You could easily buy 9 and still save money. I leave one at work, keep another in a planner and one at home with my other pens. I also use iron gall inks in many pens and it's good to have an inexpensive pen to use them in to avoid the acid levels from damaging better pens.And apparently people want these to be pocket pens or complain about the filing mechanism.... they're fountain pens, they make specific fountain pens to be carried in your pocket, buy one. And the filling mechanism could be operated by a child, I've let my niece do it, if you can't figure it out, don't buy the pen. It's simple, pull and push.
