What’s your favourite that you want to share? Let’s hear them!
My absolute favourite hack is for people who don’t own brass shims to floss a nib that has collected a lot of paper fibre. If you get mail with a plastic window, you can carefully trim a strip long enough that you can hold between your fingers so there is tension. This is often enough to floss a tine.
If you’re an occasional sample user that tends to forget about using them, have a nice eyedropper in the collection. I’m not a huge samples owner and a little forgetful, I found my samples started evaporating before I finished them. Things changed when I got an Opus 88 Demonstrator. Now when I get a sample from a local swap meet, I can drop 3.56ml into the tank, so often that’s an entire sample.
I never buy samples but I always decant some ink in smaller containers so I don’t contaminate the bottle with dirty pens (some inks are too annoying to wash out completely as well), your trick sounds good to me. If ink dries though, usually you can go back to the previous level by topping it up with distilled water, it might need some vigorous mixing and/or a day to go back to a solution close enough to the original.
I’ve had moderately good results with ink that’s 50 years old doing this.
