SHIMAIXJYY 20 pcs 0.7mm Black Color Replaceable Ballpoint Pen Refill School Office Supplies(4.2 inch)

I refuse to throw pens away once the ink runs out...a refill takes up far less space in the trash. I put these refills in my pens which no longer had ink, and they work very well. Also far less expensive than re-purchasing the kinds of pens I had. Delivery was fast. Price was good. Quality very good.

I have a few ballpoint pen cases which needed 0.7mm point refills and would not fit 1.0mm refills, so I purchased this, and it fitted perfectly in most of my ballpoint pen cases. It also writes smoothly and works well. It would be nice if they made this same length in transparent refills instead of being opaque but overall, for the money this refill does write smooth and is good.

These work wonderfully. I love the way they are packaged making it easy to just remove one at a time and keep the rest secured in a small pack.

These popular but hard to find pen refills seem to be working out great! Price was decent.

Writes too thin.

These are of no use. Did not fit my pens. Too short. I hope for refund for return

Me encanto como escribe y su color azul, pude reemplazar la tinta para unos Bolígrafos

It Fit perfect. I have several pens that I like because of their size and feel and want to get them. You must accurately measure , length, diameter, etc. the original cartridge before ordering. I use a micrometer and fine ruler. It writes smooth, but not very smooth, thin blue line. I think its is not as smooth writing as the original cartridge, but it will do.

Good package. Works well. We have extended the life of our favorite pens :)
