I bought these markers to decorate a plain orange pair of leggings for a contest. (See pictures!) I loved having the two different tip widths in the same marker. The fine tip was perfect for outlining my designs and it was nice to have the wider tip for coloring in larger areas. Through roughly 6-8 solid hours of use, I never experienced any issues with the marker drying out, bleeding, etc. It worked perfectly! The only thing I haven't had a chance to test is to see if the designs I drew will hold up well once the leggings go through the wash. If I have any issues, I will update here!
