Hi-Tec C Coleto Gel Ink Pen Cartridge 0.4mm 15-Set One of Each Color Ships from California by Pilot

All of the cartridges write and all colors were there. They all write really smoothly and fit perfectly in my 4 in 1 Hi-Tec C Coleto multi-pen shell. All of the colors are visible on the first stroke, no need to rewrite, even the yellow shows up well bc it’s a orangey yellow! Be careful not to push on the plastic piece that allows you to click the color up or down when it’s inserted in a multi-pen shell tho. That clicker is only attached to the ink cartridge by a tiny tiny piece of plastic and can easily break.These are the smoothest gel pens I’ve ever used!

Put them in a Pilot Coleto 1000 multi-barrel pen with some blue-black refills. Perfect pen.

Write very smoothly, and the color is intense!But I’m a little disappointed as the colors are not all what is represented on Amazon. I did not receive a yellow, but another kind of blew my least favorite color.

Very smooth writing gel pen refills. The ink color is saturated and distinguishable. The grouping is a great way to try out colors. Very satisfied.

Love the vibrant colors. 0.4 mm size allows me to write very small in my margins. Easy to change out.

The pens came just a described. The 0.4mm is a lot easier to write with than the 0.3mm pens that I purchased.

I'm currently waiting for the pen barrels to arrive so I can use these (different purchase), BUT not all of the inks I received are a .4 tip.2 are .3Minus 1 star for inconsistency :/

Everything was fine except this was not the product listed. The listing and image specified 0.4 mm refills, but I received 0.5 mm.
