What on earth makes you think Instead is messy? I just got done looking at the site, and I didn't see anything about it being messy. And you CAN wear Instead for 12 hours; says so on the site and on the side of the box.

I guess I look at it this way, you're going to have to pull something out, you know? Pull it out, wash your hands. Instead and my Luna isn't any messier than a tampon string.
