30 Piece Black Ink Pen Refills, 1 mm Ballpoint Refills Replacement Ballpoint for Click Retractable Pens Office College Supplies

Good option

I have only used 5 so far so honestly cannot review the longevity of use. Easy to hold? It is a refill. I do recommend that you have a razor blade or exacta knife when replacing the refill to trim the rear portion. careful disassembly of the bad pen since it may have many internal little pieces.

I bought the refills for a favorite pen. Not all refill are a like. Some leak out faster, some did not roll easily. Still cheaper then big box stores or the cost of replacing my pen.

Well done. Comes in a nice box to keep extras in. Clips easily to fit multiple style of pens. Nice tab on end to protect ink and point til ready to use. Immediate good flow once all set in the pen.

These refills are great and fit a pen that I have had a hard time finding refills for. Cut them down to any size you need.

These refills fit my standard ballpoint pens with a little snip off the end. Unfortunately, the ink doesn't flow smoothly. They're okay for jotting down notes, but I wouldn't buy this brand again.

Works as expected with quick delivery.

The ink is quick to use up. It maybe lasts 2 days. I have to refill my pen so frequently this whole pack is only going to last 2 weeks.

Delighted with these refills. Just what I wanted. to be able to use the many ballpoint pens I had without refills over the years.
