Would someone please explain how this works? i understand a converter is used so i can use other bottled inks. how do i use it?

Put the converter inside the pen (just like a cartridge), put your pen's nib inside the bottled ink, and then screw the converter's screw mechanism at the back, It'll vacuum the ink into the converter just like a syringe. Tip: for a better fill, screw and unscrew a couple of times so no air is left while filling.

Will it fit in a pilot Kakuno?

Yes. The con-50 and con-70 also fit. The con-40 replaces the older con-50

Will this fit pilot mr animal collection?

This converter fits all modern Pilot pens, except a few sold in parts of Europe which are altered to take International style cartridges. I'm not sure if those can take a Pilot converter.

Does it work with any pilot fountain pen?

No, this does not work with all Pilot fountain pens. I'm not sure how familiar you are with fountain pens, but some fountain pens, like the Pilot Custom 823 have built in ink receptacles that are vacuum or piston fillable. So you couldn't use this converter with those. But you can use this converter in any Pilot pen that uses ink cartridges.

Don’t buy. This doesn’t fill ink as mentioned.

Poor product. Don’t buy.

Den tar inte upp bläcket. Fick fylla den med en spruta… Dåligt, eller så gör jag fel? Provade att fylla med konverter installerad i pennan och direkt med bara konverter. Samma nedslående resultat. Sailors konverter fungerade hur bra som helst… Pilot, dåliga toleranser???

Dieser Con40 Konverter ermöglicht durch seine kleine Füllmenge öfter die Tinte zu wechseln wenn man möchte. Das kommt mir persönlich sehr entgegen. Für etwas längeres Schreiben wünscht man sich eine vollständige Befüllung des Konverters! 2. Foto: zeigt 1.Füllversuch- die Tinte reicht kaum über den Rand des Griffstücks hinaus. Noch ziemlich viel Platz im Konverter, die man auch mit Tinte befüllt haben möchte! 3. Foto: der entnommene Konverter lässt sehen, wie wenig Tinte beim 1.Füllversuch aufgezogen wurde. Da ich diesen Vorgang bereits kenne ( Griffstück und Konverter wieder zusammen stecken) alles sauber machen: ich halte das Griffstück mit Feder nach oben in der Luft mit etwas Schwung nach unten schwingen/ oder solange an das Griffstück klopfen bis die Tinte auf den Kolbenboden fällt. 4. Foto Jetzt Konverter entnehmen ( Papiertuch bereit halten) und vorsichtig die Tinte zum Rand des Konverters hochschieben mit der Drehfunktion des Konverters. Achtung: Dabei können Tntenblasen herausplatzen! Papiertuch! Die Tinte nur knapp bis zum Rand schieben ETWAS PLATZ LASSEN! Konverter säubern und wieder in das Griffstück einfügen. Feder nochmal in das TINTENGLAS eintauchen und Tinte aufziehen. 5. FOTO zeigt die vollständige Befüllung des Konverters bis zum Anschlag!

Fantastic for ease of refilling but not a huge ink capacity.

Excellent product - fits my Pilot Kakuno fountain pens perfectly. I can now use any colour ink directly from the ink bottle to fill my pens. Very easy to use - happy with my purchase! I bought the 4 set which is a good value.
