Excellent Buy!!
My new favorite pen!! I accidently found my first pen after a meeting and immediately fell in love. I was able to find them on Amazon at a great price. Highly recommended due to excellent quality. Eraser doesn't leave residue.

An upgrade to my favorite pen!
I hopped on the Pilot Frixion train last year when I needed to take a lot of notes for work in a short period of time. I wanted an erasable pen that erased cleanly, but I also prefer a fine nib (usually .05), and wanted a smooth ink and legible end product. I picked up a multipack of these pens from a department store and was instantly hooked. I told all my office-mates.I used an entire pen in 1.5 weeks for my note-taking efforts and thoroughly enjoyed the experience. The ink erases cleanly 3-4 times before you encounter re-write issues (skipping, spottiness, smearing), and the cartridge lasts a long time for my general writing needs. The ink is quick drying, with no smearing after about 5 seconds. I will note that different ink colors varied in performance, with the green skipping a bit, and the purple and navy being very smooth. The black isn't as saturated as I would like, but it's definitely legible. The barrel and grip, although looking rather chunky, are very ergonomic- I rarely got hand cramps despite hours of frantic note-taking. A total win.I decided to commit to a single color for my day-to-day notes and planner pages, and settled on the Navy ink color and purchased this multi-pack. A quick note here- these are the Japanese version (obvious from the stock photo) and not the American version. You'd think that wouldn't make a difference, but it totally does. The Japanese ones I received are better; the ink is smoother, they seem to erase more cleanly, and they are free from the tribal tattoo design that all of the Frixion pens sold stateside seem to have. In short, I love them. I'm so excited to have replacement cartridges instead of needing to buy another entire pen when the ink runs out. I happily use these pens for all of my daily writing tasks now. Highly recommend!

Great Ink
I’m obsessed with the color of this ink - like a midnight blue. Ink looks perfect on my cream planner pages. Erases well with lots of friction. The pens do rattle when you use them. Small Japanese writing on the barrel which I think is cool. Able to write fairly small and slowly for darker lines without bleeding and it still looks legible. Nice flow. I can see where this would smudge with a leftie if you are writing slowly with more ink flowing out. Has actually improved my handwriting which is really something. Haven’t tried the refills yet but I read if they ever got hot the ink wont show up - supposed to put them in the fridge or freezer for a while and they will be restored.

Longer-lasting
These are longer-lasting than the ones for sale at the big box stores. Worth the extra price for the refills and the quality.
