will sharpie markers work on glass jars?

Yes, of course. However, you can buy sharpie markers that are highlighters and they would not work. Just check to make sure that it says permanent marker on them. And, like someone else said, if there is a chance you will want to use the jar again for something else, you should use tape so you can peel it off when you are finished using it.

As long as the glass is kept dry yes, but due to the "smoothness" of the glass it will NOT be permanent.

Yes, but it might be wiser to write it on scotch tape and then stick it on the jar.

it's depends on what brand

yepp :DD

**** U IT DOES WORK U DUMBASS IDIOT
