Tombow0.7mm Black Ink Refill (BR-SF33), for Airpress BallPoint Pen (BC-AP) , 3 Pack/Total 3 pcs (Japan Import)

I originally used these pens for geocaching but then found it is also perfect for my work too. Each refill lasts me around 3mths and so having 3 will keep me going a while now.Fantastic product

Japanese.Quite expensive for what they are.Apparently pressurised by the action of the pen.But by God! I love those stubby Tombow pens with their grippy clips,bright colours and transparent panels,and their ability to write at all angles and in the great majority of conditions! And these refills fit like a dream, are easy to insert and remove,and put down ink in the highly efficient way that I have come to expect from Tombow!And that,friends,is why I am more than happy to keep buying these little refills. The smile that using the pens puts on my face makes them worth every penny.

Nice pen, comfortable to hold with a flexible pocket clip that is useful. However the supply of ink could be a little bit more generous.

I have used these before and will definitely buy them again

Good.

I love these pens and the refills are spot on, no issues with them.

Ok, I’ve been using these for years. I work in outdoors so wanted a pen the writes in the rain, and vertically (leaning against a wall etc) and doesn’t leak in your pocket which normal pens do frequently when in your pocket.This pen refill is just the job, I was using a space pen but those refills are much dearer. They both suffer from being dropped on the nib like any pen, so you need to replace the refill.For outdoors work they are great, does what it saysPro’s: light, always works, doesn’t leak.Cons: not much ink.

I use these pens when doing bird lists , taking pen out of pocket and it’s ready immediately rather than waiting for the ink to settle . When they run out the refills are much more cost effective .
