Monteverde Mini Ink Converter, White (31072)

I got this to go with my Schneider Ray cartridge rollerball, which works perfectly with this converter. It doesn't hold that much ink, having a noticable air pocket after filling; but i'm not constantly writing things down,so I can go a while before refilling. I had to order a second one, and the second one was crushed in shipping, but that's because it was not in any sort of protective container, so the side walls are partly fractured and the mouth is oval shaped, but as it's not the fault of the manufacturer I will not deduct a star.

This works very well for Kaweco pens, but, unfortunately, it will not fit into a JPL Classic Indigo. Not a problem, really. I just wanted to try it out.

I bought this to fit in the Kaweco Classic Sport Clear Fine Point Fountain Pen - KWCF-CL-F , and took a gamble based on reviews. It did not fit in this pen -- but reading some of the Q&As I noticed someone mention the J. Herbin rollerballs, for which I have converters, and these fit very nicely in the Kaweco Classic Sport. The difference between the ones I got with my J. Herbin pens and this one two is about a millimeter or two of length on the open/narrow end of the converter - it just won't seat right in the pen as it is, no matter how hard I pushed. The converters I had from before fit like a glove with almost no effort. Funny thing is that the converters from before (with the J. Herbin pens) are also Monteverde Mini-Converters, so I don't really know why they're different. They definitely are very slightly different, though. I'll hold on to this to possibly use with another pen in the future - I have a skyline in the mail, and maybe that will fit. Photos to follow.

The 2 that I received are NOT International Standard sized! They are unbranded Chinese Standard sized. They do not fit in any of my Monteverde pens.

If you want to fill your pen with ink but your pen only accepts short cartridges, this converter is the one for you!

Tiny but easier to refill than a reusable ink cartridge in pens that are too small for a standard international converter. It’s a trade off on ink quantity.

This is the perfect size for my Herbin Jacques Ref 21677T pen. It doesn't leak. It holds a good amount of ink for the size. It is a durable product. I consider this a good value. Using a ink filling syringe it is easy and mess free fill.

This isn't necessarily a fair review for this product which I'm sure is a fine converter for a monteverde pen. But for my kaweco sport I couldn't get it to fit. Even read a review saying you just had to press hard until it pops on. Never got it to work. Back to cartridges while I wait for a converter to come, and might even just use the needle method.

私は雑誌の付録だったミニ万年筆を普段持ち歩いているが、そのミニ万年筆は「カートリッジ」式なのでインクが無くなるとカートリッジを購入しなければならず使えるインクも限られてしまう。そんな時にこの製品と出会いダメもとで使ってみたら私のミニ万年筆にピッタリ！ 吸い上げ式なので気に入ったインクを購入して入れられる。これで字を書くのはもちろん絵を描くことも出来る。とても素晴らしいモノなので今回の購入で2本目。

It is expensive for its size. It is not even the size of a standard cartridge. Most of these shipments from US/UK in Amazon is disproportionately very high. These external sellers are making fortune. Other thing in terms of the product itself, it does not look like a screw type although you see threads, irrespective of it, a light push is all that is required to move the piston. You can see in the picture, how small it is.

Works perfect with my herbin rollerball. Now I can use fountain pen ink with it!
