O-Refill cartridges for OPen 2 and OPen Pro, and OPen Mini

Bought as a spare for the Mini version of the pen. The included refill is small, hard to say how long it will last, so it's better to have a spare. They write very pleasantly and smoothly. It's a pity there's no blue version, because that's what I like.

The refills are fine. I bought them as a spare for my Olight pen 2 mini. It's worth having extra refills, because you never know, and the manufacturer may change the offer, and one refill in the set is a bit too little.

The refills are really excellent. They are very comfortable to write with in my Mini 2. And now they're available at an even better price. In my opinion, there's nothing to hesitate about. I definitely recommend this product and the store militaria.pl.

I bought refills as a backup for the OLIGHT O'PEN MINI 2 BLACK pen. Both the refills and the pen are very well made, they write clearly and are efficient. Plus, the price is reasonable. I recommend them.

They work perfectly, I recommend them – they don't leak, start writing immediately, write very softly and clearly. They're comparable to refills from well-known rollerball brands, and this company, as always, performs excellently.

I bought them as a spare for the Olight O'Pen mini. I checked them and they write really great. Especially happy I managed to get them at a promotional price. Delivery was, as usual, fast.

I bought spare refills for the Olight Glow Pen. While I'm at it, I recommend this pen to anyone undecided. If these refills write as well as the one that originally came with the pen, they're definitely worth their price.

Black gel ink refills work great for daily use, as well as in the field. I will definitely come back to them.

Perfect addition to the Olight pen. They write well and are solidly made. In my opinion, the price could be a bit lower, but as a replacement, they're worth it. I recommend buying.

Very good quality, fits perfectly to olight2 pro, writes great in all conditions and doesn't leak like other refills. At this price, they're only available here.

Refills with black gel ink and a ballpoint dispenser are designed for Olight pens with flashlight. You can write with them in any position, the ink doesn't leak, and the writing comes out very smoothly.

They write well.

It does its job excellently, I definitely recommend it.

They fit and write without issues, and the price at militaria is attractive.

Interesting gadget. The price may seem high, but I still think it's worth buying ;)
