When I make pens for fundraisers I like to use the highest quality that I can afford (usually Dayacom). But most of my pens are given away as gifts, so I like to try to keep costs low. I really like the Zen, but prices have gotten kind of crazy. Has anybody used the magnetic from PenKitsMall (https://www.etsy.com/listing/684892...-fountain-pen?ref=shop_home_active_19&crt=1)? How does it compare to the Zen? Also, any thoughts on the other kits from PenKitsMall?
