"These are great markers and last a very long time, especially if u keep the lid on when you aren't using. Great for posters and billboards. Or kids projects. We have been using these for years, and will continue. Its a simi- fine point and very easy to write with and accuracy. They are a great value for the money and we never worry about them leaking. Ink flow is fantastic."

These sharpies are great! They are permanent, dry very quickly, do not bleed, and last several months or more (depending on use). The caps closers tightly, which keeps them moist and prolongs their life. They are truly fine point and can be used oh pretty much any surface. They write cleanly and clearly and don’t smudge. They are a dark black color, as I expected. They are a good value for the money because they are such high quality and last a long time. They are thin and lightweight and very easy to write with. I will definitely buy them again!Anonymous
