Pilot Hi-tec-c Coleto Gel Ink Pen Refill, 0.5mm 15 Color Refills, Sticky Notes Value Set

I was very skeptical that this would work, as there were so many mixed reviews. I am so pleased that I decided to at least give it a try, and I am certainly glad I did. The pen works splendidly and the eraser if perfect. I didn't have any trouble getting the mechanism to work and adding the inserts were a breeze. I highly recommend this to anyone who likes having the availability of a pencil along in the convenience of the Coleto Pens. I am in pen/pencil heaven!

This is so perfect to go along with my other coleto pen refills! I love these pens! I have the 4 color pen and it works great! It doesn't get better than this :)

Great refill option. Smooth and exact writing.

I love the .3mm coletto cartridges: they may not be the most luxurious writing experience as they're a bit scratchy but are extremely precise and are the only ones that last. Everything a multipen cartridge should be.

It’s nice to add a pencil and eraser to my Coletto. However, these are pricey.

Absolute best refills!

love it. I like having them at my figertips in same shell as the pen. I pprefer pencil, as I make a lot of mistakes.

I love these pens. They came wrapped nicely and in great working order. Package was new. Package arrived as advertised within the advertised delivery time.

Searching for the refills and these were the cheapest at the time of the purchase. All of them looks good

Great product! Fast delivery.

These pens have great pigment and are very smooth writing

I love this whole line, the ink is smooth, the pens are easy to refill and reload, move around, customize, etc.

I personally like the 0.4 point. But I just runs out of the ink fast. It lasted me only 3 weeks.
