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.

コンバーターは、インクの使い切りまでが長いため、小型の40を選択。赤や青、古典インクまでいろいろ入れて使っています。中に入っている球が動き回ってインクの使い残しが出ないように働いており、細かい球が複数あることで角に引っかかったインクも書き出してくれるため、無駄なく使い切れると思いました。封をする玉一個で動くものもあるが、角にインクが残ることがあり、玉の数と大きさにもノウハウがありそうです。接続が合うならば、他のメーカーのペンにも使いたい。

インクコンヴァーターは他社製品を含んで何種類か使っていますが、インクの容量が少なめなのを承知さえしていれば使い勝手など特に問題ありません、それにデスク型のぺん軸に入るのはこのサイズしかないのでともかく納得して使っています。

ＣＯＮ２０，５０が廃盤になるという事で１０本ずつ購入しました。そして後継品のＣＯＮ－４０を５本購入しました。いかにもちゃちっぽい感じもしましたが、拡販用の玉が入っていたりプラスチッキーながら部品が一体化しているので、故障もなさそうです。吸いこみがいまいちな感じですが、０．５ＭＬから０．４ＭＬにダウンサイズされています。これにＣＯＮ－７０も対応できるとのことで今まで何だったのか？と疑問に思います。どれくらい持つか確認してみようと思っています。でも、ゴムと鉄製のものは淘汰される運命なのですね。胸に差すと少しこのベアリングが気になる時があります。

万年筆の魅力の一つは自分の好きなインクで文字を書くことです。やっぱり数あるインクの色からこのコンバータで吸い上げて使うのが楽しいです。

万年筆マニアです。パイロットのキャバリア用に購入。ちなみにキャバリアは安くてペン先も硬く（硬いペン先が好みなので）インクを替えて二本目の利用目的で購入しました。インクの容量は少ないので単色で使う人には頻繁にインク補充の必要がありそうです。私はいろんな色を使うので容量が少ないのはあまりマイナスにはなりませんので。商品的に「大満足」ってことでもないので☆４つ。

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!
