Although this product is normally used for overhead projector presentations or for wet erase boards, I use the Vis-a-vis markers for writing at work and at home! I am visually impaired and cannot see writing from ordinary pens or pencils. I need bright, bold print. I believe I have tried every type of pen on the market with no luck; that is, until I discovered this product! It not only writes bright and bold (blue is best for me), the ink does not bleed through paper like markers are apt to do! This product allows me to work and make a living! This product saves on my paper usage, which in turn saves our trees, making it an environmentally sound product! The only drawback is how quickly this marker runs out of ink! (I use more than a dozen of these markers each month! Since the price of these markers are more than ordinary pens, I pay more to write, but to me it's worth it!!! I can see what I am writing! Thanks for a great product!"..." Read more
