Parece de buena calidad, pero los pedí para unas plumas Parker y no son del tamaño para esas plumas

Very easy to use, no dripping at all.

These cartridges are very handy for use in fountain pens type Baoer 3035 Stainless Medium 0.5 mm Nib Fountain Pens. Their replacement is fast and comfortable.

Dear friend I haven't receive the item Can You say me where staying in your shipping? Friendly Manuel

For the price these are great. Lets you use your fountain pen without the guilt of having to use disposable cartridges.

If compare with other Fountain Pen Converter Taking Ink Cartridges. It is quite expensive but good appearance.

works well with Picasso fountain pen, but i used a piece of paper (gasket), because the converter is a little too thin

Good price, but doesn't seem to fit any of my pens - including the Hero pen that appears to have a similar converter already supplied

Gute Ware, macht das was es soll - nämlich Tinte aufnehmen - für den Preis unschlagbar.
