Retro 1951 Short Capless Rollerball Ink Refill Fine Tip, Schmidt P8126, P8126 Short Blue, 2-Pack Schmidt Capless Roller Ball Refills, fits Retro 51 Tornado Roller Ball Pens.

So happy we replaced the ink in our fancy pens. They write so smoothly with plenty of ink. Very happy and would highly recommend.

I’m not a fan of black ink so ordered these with my pen and couldn’t be happier. Writes great with little to no pressure and puts down a nice consistent line.

I purchased a purple Retro 1951 pen many years ago and could not find a refill until NOW. The refill fit exactly and am so excited that I now can use my pen after so many years of just looking at it.

These were supposed to be a fine point. Medium was sent. However, beyond that, the ink glops out of the refill and it's a terrible mess. These do not write cleanly at all, and the flow is very inconsistent. I was sure to use these at room temperature and it did not help with the ink flow. These are going back.

Fits my favorite pen and writes good

Being the Retro 51 brand replacement they maintain the quality of the brand.

Era un repuesto q andaba buscando hace mucho tiempo

I ordered 2 of these refills in February. The 1st refill worked ok, but with extremely limited use ran out after about 2 months. I recently tried to use the 2nd refill and there wasn’t any ink in the cartridge. I reached out to the distributor and was told the issue could be because the items were shipped in a thin plastic bag and that the refills should be protected. If this is the case, the distributor should ship the refills in better/more protective packaging. My advise to anyone buying this product is to test out both refills upon receiving the items to make sure they both work and if not to get a refund immediately.
