MANUSCRIPTPen MC0401CB Fountain Pen Ink Calligraphy Cartridges, Black, 30-Pack

The size is perfect for the majority of fountain pens. The ink is good quality and flows smoothly. There is no leakage at all. And the package clearly states NON Waterproof, which isn’t a problem for me. Came quickly!! I will definitely order again.

I’m taking a calligraphy class and my school was charge too much for this, it is a great price and works even better than what my school wanted me to buy

I would love instructions for the use of them as I know I have the pen for them but don’t know how to use it. I would love trouble shooting support or directions for ink not coming out as it leaves a lot of room for my error to repeat and get this product bad reviews for user error.

I rely on these Manuscript Calligraphy Ink Cartridges all the time in my calligraphy work. The ink flows in the exact right amount and never blobs or runs! A first-rate product.

The cartridges are perfect. I was having a very hard time looking for ink cartridges for my Fountain Pen. I was skeptical of them at first, I'm on a tight budget and I didn't want to go broke buying duds. However they fit perfectly.If you have an AmazonBasics Fountain Pen. Look into these cartridges as a possible investment. They were just fine.

Ink cartridges are just as described and the shipment was fast.Great job. Clean ink that works well in my Amazon pen.

I've learned not to cheap out on ink cartridges if i value my fountain pens at all. i thought it was all the same stuff so it wouldn't be a big deal, but it made two of my Wordsworth & Black fountain pens unusable when i installed it, as it somehow clogged the chamber. I was quite upset.

This works great for my calligraphy pen. There's a lot of different pen sizes so just make sure it fits yours.
