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.

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.

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.

good fit and useful pen maintenance tools

Items arrived promptly and were as described. Hey, it's a pen wrench, so there's not much to write. Single purpose tool. But when you need it, you need it.

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

Good news - this is the right tool for your Asvine fountain pen. Bad news - you probably ought to not disassemble your pen very often or you'll have problems with the plastic threads.

Works well, easy to use
