Lamy Cartridges Refill, Blue, 5 Pack (T10BL)

Quality ink and it was difficult to find in stores. A good red color and easy to insert.

These are great cartridges that are so well designed. They don't drip or leak at all while in the pen and you're writing, and they don't drip or leak while you're putting a new one into the pen as a refill. It goes along with the great design of the calligraphy pen for which I bought it. I love both of them. When two of my students, all of whom have learning disabilities, saw how the pen wrote, they wanted to learn how to write in cursive. I let them work on their cursive for which I bought books for them, when they focus during their lesson. They did so well that I bought them each a calligraphy pen and two boxes of these great refills as a reward for their diligence. They take more notes in classes now, writing in cursive, and keeping their cartridges nearby in case they need them. They are simple to use and insert into the pen, which is why I liked them for these students. Nothing complicated. No mess. No leaks. Just great cartridges that started a revolutionary move in my students. All because of the way they saw me put these cartridges into my own calligraphy pen! How much better a recommendation can you get than that?

Good good quality ink. Affordable too. I used to be one of the snobby types who filled their own ink cartridges but I realized, in the end, that I just like Lamy ink! Actually I love it. Even the graphic design-work is great. Double fun: feel like a hipster and actually have a great pen/ink at the same time! Highly recommended. They last a super long time. I write a decent amount with my LAMY every day, and as of a few weeks in I still haven't run out of ink in my first cartridge! I figure later in the year I will order another box (it did take a few weeks to come in from Germany). Do it! You won't regret it! It's also a beautiful rich shade of blue. I lean towards black most of the time, but I like being able to really see the blue ink and see the kind of writing you can only get with a fountain pen of quality like LAMY's.

These work quite well, and as they are pretty much the only option for a cartridge for this pen. The ink itself is a nice dark shade of blue, which I prefer it seems to dry relatively quickly. I’ve not had any problems with them leaking. One thing that I do like is the fact that they have a much larger capacity than most other ink cartridge. I wish that they had a more varied selection of colors however. If you purchase a converter, then this is no longer a problem however, I do like having cartridges for a quick fill as I use this pen a lot when I’m out and about, and it is not always convenient to carry a bottle of ink with you. That being said, they work well and decent value value for the money

I received 2 Lamy fountain pens as gifts and I love them! I love the ink too; Lamy ink is smooth, clear, and bright (best of all, it comes in various colors!) The refill cartridges are super easy to replace: unscrew the top of pen, remove the old cartridge, replace with the new cartridge, screw the top of the pen back on until you feel the cartridge being "pierced" by the top of the nib & you're all set!! I love the diverse array of colors. I'm a teacher, so I use one pen with this blue ink for personal notes, signing docs, professional purposes, etc. & and I use the other pen with more vivid inks, like purple, teal, and red for giving feedback to students. Overall, the quality of the ink is very good -- it dries quickly enough to avoid smearing, but is still bold in color. While the ink does bleed through on thinner paper (something to consider for writing on two sides of lines paper, for example), it works great on higher quality paper or for single sided writing purposes. I've purchased several Lamy cartridges over the past year and I've been satisfied with all of them. Other than the bleed through on thin paper, the reason for my 4 / 5 stars is because I tend to go through 2-3 cartridges per week for a single pen since this is the primary pen I use. Still, the value is good and the quality of the ink is what makes this a worthy purchase.

I bought this package of cartridges for a red Lamy Safari fountain pen that I purchased for grading student papers. It's a classic red color, and writes relatively smoothly on copier paper (though there are smoother inks out there). A good proprietary cartridge.

Fits my LAMY and was easy to put in and get it writing.

Perfect condition and quickly writing again. Lamy had great products!
