I quickly found that these pens have the worst tip for writing and have no idea how to refine the tip. I found it annoying how poor a quality the pen was for 14 bucks and regretted paying it when I saw how awful the application was. Thank god there's a Micheals in town because I went there, bought sharpie paint pens and refilled in my tires and now it looks respectable.
Came in the mail, very excited to get it, went to put it on tire, and nothing, it was dried up...completely, Cracked it open, and rock solid. Not entirely sure why it was so bad, but once I opened the package, no returning it for me, what a wast of 10 dollars.
