Hongdian Fountain Pen Set Ink Cartridges Blue Color, Pack of 30 Ink Refill Cartridges, 3.4 mm Bore Diameter

good value

Smooth flowing ink - they fit my italic fountain pens perfectly.

Unfortunately, this doesn't fit my Parker fountain pen. Probably my fault, I presumed it would be compatible.They came well packaged and the product looks good. Just gotta work out what to do with 30 cartridges !

Delivery was fast, works well with my fountain pen

fits the Hongdian pen most securely

I've bought cheaper cartridges in the past. Since I have just bought a Hongdian pen I thought I would try these recommended cartridges. I was surprised to find that using these black cartridges made my other black ones seem dark grey. I don't know how much the compatibility of pen and ink to each other caused it, or whether it is just superior ink. I shall continue using these for the Hongdian pen and I intend trying them on other suitable pens (3.4mm calibre).

This ink has a nice flow to it. The price is good, though I wish there was an option on a slightly longer cartridge.

Good colour. As described on the description

If you like writing or drawing with an ink pen like me, this is a compact alternative to carry with you.The big bottles of ink are practical to recharge at home, but not if you are going to a train or airplane trip (specifically airplane if you consider the ink as liquid). These ones do the trick.And I know it’s plastic, but afterwards you can easily recycle it!Just be sure that this one will fit into your ink pen!

Buon prodotto che risponde pienamente alle aspettative.

Muy buena calidad.

Utiles pour un stylo de marque chinoise au lieu de remplir le réservoir du stylo.Attention ne convient pas aux Waterman etc...
