Mitsubishi Pencil Uni-Ball One UMNS38.24 Gel Ballpoint Pen, 0.01 inches (0.38 mm), Black, 10 Pieces

Love these refilled they are an excellent value for your dollar and fit perfectly in my uniball ball point pen. I love that they are .38 mm. I only wish they held more ink. I use them for EVERYTHING and do a lot of Bible study, sermon notes, and other writings. The ink flow is amazing the the quality and durability are great. I think of 2-3 purchases I had issues with one of them. All others have worked fine. These are my go to pen refills. I love the design and know that they fit my pens. If you love writing with a great pen and like very fine tips these are the best

The work with both the small and tall pens from uniball. Great quality pens and these refills make it so that i can keep using them without have to throw them and buy.

Some of my favourite pens have refills! I love my Uni-Ball pens. The fine tip and smooth writing means I always have one with me. Being refillable is a big plus for me and it fits in both the full size pen and the shorter pen. Refills cuts down on plastic waste so I don't always have to buy new pens.

Good pens from uniball. But the .3 might be too thin for my writing style in the field, one roller already stopped working. Otherwise the pens wrote smoothly while they still worked. Love the different colors

Good quality ink

The ink flow smoothly without cutting the paper.

I love how effortlessly these pens write. They don't smudge and the green is so dark that to an unsuspecting eye just looks black. Can be used for checks or anything else you want. Super comfortable in the hand as well. I keep one in each car and all over the house because I won't use any other pen if I don't have too. I will buy again!

Worked just as intended
