I am obsessed! I use a whiteboard calendar to keep track of bills, activities, appointments, etc. but my board isnt the biggest thing in the world, so having fine tips on my markers like these have made a world of a different and make things a breeze! They are supposed to have less of an odor, which honestly, I believe they do, they are definitely not as strong as most dry erase markers! They write well but I do wish they were a bit more bold (this could be my fault of not writing hard enough). I would love to find these in more colors besides black, blue, green and red though!
