Outus 60 Pcs 0.7 mm Black Retractable Pen Refills Bulk 4.2inch Replacement Ballpoint Ink Pen Refills for Click Ball Point Pens School Office Supplies

works perfectly for office pen replacement

Fit the pens and works good.

They write good & the plastic tubes which can be cut with a scissor make them easily adjustable to fit the pen

So far work great,& easy to trim to size if needed!!!

Inferior product ,lousy ball tip ,lousy ink….you get what you pay for…dumb purchase by me….

Many of these ink refills skip & do not write consistently. When they do write, there are random blobs. Also, they are advertised as fine point, but they really are not. I would not order these again.

I have a pen collection and I can keep my pens cause they unique pens and I need refills to keep them

Glad to have on hand.

Having kids at school can get problematic keeping up with the steady stream of pens required. this is a handy and dare i say more environmental option ( its nice when you can save money by "going green") so now they churn through these and can quickly renew an old pen, which was great as they always have a favorite that just feels right.

these refills were not what I wanted as they are way too small fo0r the pen, can't find the right pen for them on amazon w`as a waste of money

These pen refills are shorter than a standard refill and you get 6.5cm of ink. If you are making resin pens, the refill is too short to engage in the holding tab at the end and therefore 'floats' loose and can stick out through the side of the resin pen. Having said that, all the refills I have checked write well. I bought cheap as I'd not made pens before, so these are great as a starter.

All as described .... :-)

Why throw a good or a prepeinted pen away when you can eeuse it for only a few pennies
