I use Sharpies a lot, for many things. I have them in all different colors and tip sizes. It’s nice to have these sharpies with the different size tips in one marker. It saves space and I don’t have to go hunt for each when I need to use them. The big tips are good for marking on boxes, and the small tips are good for writing in cards or address labels. When you do a lot of packaging it’s really nice to just have one marker on you. I will always trust the Sharpie brand and I haven’t found an alternative permanent marker that even compares in quality.
