i've had it for 6 months now and have never taken it off before. now that i want to, i don't know how. i don't know which ball to turn or in what direction. i've twisted them both in both directions but i think i might be tightening it, if anything haha. i don't really have to take it off but since i haven't before it's just something that's bugged me and it might suck if i have to take it out for work when i don't know how (since i can't tuck this one in on account of it's thickness).
