Liquid Gel Pen Refills: Fine Point 0.5mm Black Ink Twin-Ball Nib Refill Multi-Compatible with Retractable Click Pens Quick Dry Smooth No Smear Smudge for Writing Sketching & Taking Notes 8ct

These are great for the price. Had a favorite pen that ran out so I’m glad I can get quality refills!

Bought these to refill some custom resin dipped inkjoy pens, works great!

Bought these as a an accessory to other writech pens, and I must say I love that I can buy refills for my pens. The ink flows very smoothly and doesn’t skip.

Smooth writing doesn't smear overall a great pen

Bought these as refills for the soft grip pens, they do not fit. Too large. A little annoyed, because the photos and description clearly says they do.

Work real good and are consistent. A lot cheaper than buying new pens every month with how much I be writing.

I bought these as a refill for my favorite pen by Writech, the gradient pens. Even though they are .7 pens, the barrel of the ink refill was the wrong size and would not fit. I did put one of these in a Sharpie S-Gel though and it fit perfectly so l’m happy I get to use the ink.

I love how smooth they write
