These are just plain convenient, and hold much more ink than the converters.
My five ink cartridges I’d ordered came well packaged and on time. It’s nice to find cos. that still operate w/integrity (increasingly rare these days).
Love supporting small businesses and writing in fashion. Product arrived SO FAST! For whatever reason I was worried if legit. My Lamy is awesome and perfect.
Love the LAMY cartridges, especially the blue-black. Still new to the fountain pen world and have several Safari models with different finishes and nib sizes. My go to in fountain pens and ink.
Excellent consistant product. Highly recommended
