Pilot Hi-Tec-C Coleto 0.4mm Aqueous Pigment Gel Ink (Metallic 6 Colors Refill Set)

These colors are excellent. My favorite is the Metallic Purple.For the Coleto, I find the 0.4 are the most reliable refill size... I've had no problem with them ever. The 0.3's are hit-and-miss, sometimes they write well, others are dry & scratchy out of the package.

I love metallics so these inserts are perfect!

Used it on my hello kitty coleto. Fits perfectly, the ink is amazing! Will buy again.

CUte colors that fit in my sailor moon pen that came with no ink.

These are very light and a little hard to see. However, the colors wrote the same color they should and they’re very fluid/smooth. Maybe buy a little bit darker of a color, in my opinion.

I love everything about these refills. They write smooth and dry fast!

The pens themselves are wonderful when they are not delivered damaged. Placed two orders and both times all of the pens were broken. The plastic bit broken off is what you use to push the ink color to use it when in the pen body. I've never had an issue with many of the other colors only these metallic colors. The Pilot Hi-Tech-C Coleto I do love.

I have ordered these types of refills before for my HI C Coleto Pen, so I know they are fragile, but NOT this fragile. All I did was slide them out of their plastic sleeve and the top colored piece came right off when I held it to put into the pen. The part of the refill that is colored and then inserts in the the tube of ink wasn't as sturdy as others I've used. Maybe that's why. I hate it b/c I really wanted to love these! I didn't get a replacement b/c I figured it's just how they are made, but I did get a refund.
