Pilot Hi-Tec-C Coleto Multi Pen Ink Cartridge - 0.3 mm - Apricot Orange

These refills are my first experience with the vaunted Hi-Tec-C. I'm concerned that these may not be writing as well as the original Hi-Tec-C pen (I've read a lot of glowing reviews). I know that is the case with the Slicci 0.3mm refills, that write no where near as well as the original barrel.

Anyway, on to performance. The ink flow isn't the best. The line gives out/sputters a lot while writing. I found myself having to slow down a little to get a good flow. Even then, these tips are really scratchy.

When the refill does manage to work, it puts down a nice, thin line (thinner than the 0.3 Slicci). The colors are really cool.

Bottom Line: These refills can't keep up with my writing speed. I need to try the original HTC pen and a 0.4 refill, to see if those will be smoother and more consistent. Until then, it's all about the .28 Signo DX.

this WILL work with the dr. grip 4+1 series. all you have to do is take the refill out of your dr grip 4+1 then take the top off of the coleto refill and make sure both are the same height (if the are not, cut with scissors to adjust) then put the coleto refill in the spot of the dr. grip.

I've had these pens for about 9 months in both the .3 and .4 sizes. I purchased all the colors in both sizes. All but one of the ink cartridges has segmented out the clear gel and ink so that I can no longer write with the pens. They are always stored horizontally, but somehow the clear gel is now between the ink and the pen tip. Do not buy, they are not nearly as good as the normal Hi-Tec-C pens. Previous to this happening I loved them and used them all the time. REALLY angry at the amount of money they wasted.

Love being able to trim the Hi-Tec-C Coleto refill and use it with the Zebra Clip-On multi pens. It's the only way I've found, so far, to get 0.3mm tip or smaller on a multi-pen.

This is my favorite ink/pen line. I use the 0.4 in black - very smooth and great for taking notes. Highly recommended.
