Wrench for Piston and Vacuum Fountain Pens, Set of 2 Removing Tools

Very useful for mai maintaining not only Asvine but also Gravitas fountain pens. It fits perfectly. I was able to open the back of the piston, clean the pen, and lubricate it. The price is very convenient for the functionality and precision I got.

Pen wrench that works on many different fountain pens. Very good value for the money. Highly recommended.

good fit and useful pen maintenance tools

The wrenches fit my Majohn 139 perfectly, and that's why I ordered them. They're very thin, but strong and well made. The thinness is what allows them to fit in the gap between the upper end of the pen's barrel and the bottom of the piston's twist cap. I found out that they'd work for my pen on Reddit and so ordered up. The price was reasonable and the wrenches themselves are well-made. They're simple in design and all one piece; they also fit the lock ring of my pen perfectly which means when I need to clean it there will not be any damage due to trying to get the lock ring loose and out of the pen's barrel. There's just one thing and that's why do they sell two identical wrenches together? Why don't they include a second wrench with more sizes to fit more pens?

At just 65mm X 12mm the wrenches are smaller than you might think. At first I thought Amazon sent me an empty envelope, but after cutting open the inner brown envelope I found another plastic envelope with the wrenches inside. I bought these wrenches to go along with an Asvine P20 piston-fill pen. One-star off for not including a wrench with the pen in the first place! Without the wrench, there is no simple way to disassemble the pen for cleaning.

this is a good wrench set for Asvine maintenance

It took me a second to figure out how it work, but I got there in the end and it work perfectly.

Very flimsy. The build quality is subpar.

Ces clefs sont parfaites (mais identiques, pourquoi un lot de 2 ??). J’ai fait confiance aux commentaires indiquant qu’elles s’adaptaient à beaucoup de marques de stylos différentes. Et effectivement une des encoches est totalement adaptée à mon Nahvalur Original Plus. Elles sont un peu fines mais les stylos n’aiment pas être trop serrés donc ça ne me gêne pas particulièrement. Très bon achat, je conseille !

Works well, easy to use

Trattasi di un set di 2 piccoli strumenti di metallo, perfettamente identici, necessari per lo smontaggio delle penne stilografiche e compatibile con la maggior parte dei modelli in commercio. Ho trovato questo accessorio molto utile.

La llave va perfecta, necesaria para desmontar y poder realizar mantenimiento en las plumas Asvine y algunas mas

These are very well made and have all the sizes to fit most piston filler fountain pens
