These are great quality dry erase markers. They are low odor but I couldn't smell them at all which is a good thing. They are vibrant colors that write and handle just like a pen. They easily wipe off so you can do it all over again! I use a whiteboard on my fridge so iuse these often. The Bic brand makes me confident that I'm using a quality product that will last. Im looking forward to trying the advanced line as well.
