Review: Works perfectly with pen from same brand - I recently bought a (very good) pen from this brand so also ordered these ink cartridges. They are well priced and come in three separate boxes which is ideal. They are easy to insert, just give the pen a gentle shake over scrap paper to get the ink flowing. Perfect fit! The ink quality is good, and a true deep black. In my pen it flows smoothly, and writes really well. I'm pleased! Thanks for reading, I hope you find this review useful.
Review: Perfect - Perfect - husband delighted with his present.
