For me the pens last about a month or so but for other who don't write as much as I do it could last longer.If you buy a special ball point pen that's always better the ink usually last longer and you can write better with them!
Once it dries
A cow will never dry up if you keep milking her. That's the bottom line.
That depends entirely on the conditions under which it is kept.
Not for long.
Watercolor typically dries within 24 hours, but it can vary depending on factors like paper thickness and humidity.
It dries out . just stays there and dries out .
Opened it will not last long before it dries out, but in plastic wrap or a container it will last about 5 days.
Store it in a cool dry place.
Rubber cement typically lasts for about 1-2 years before it dries out and becomes unusable. It is important to store it properly in a cool, dry place with the lid tightly closed to extend its shelf life.
Polyurethane typically dries within 24 hours after application.
Well, I'm guessing here, but I would recommend waiting till it dries. ;)
I bought GHS FastFret string cleaner and conditioner for my bass guitar How much does it long before dries up? How many times can I use it?
