Sharpie Twin Tip Permanent Markers, Fine and Ultra Fine, Black

Sharpie Twin Tip Permanent Markers are a little more expansive than normal Sharpies but I figure it had to be worth it for me to be able to mark the date I got something on my clothes. Yeah, that's what I use these for. I like to know how old my underwear is so I can buy more if it lasts. 

So, what am I saying? These are better than one tip Sharpies!
