Review on Pieces Metal Backs Locking Keepers by Kelly Caballes

You know I love the idea of being able to lock the pens in place and make sure they don't fall out of the case until I pick them up. BUT the problem with these products is that I can't REMOVE them at any time. It's like it's stuck to my needle forever. So one gets stuck in my pocket permanently because I decided to try the second one and now it won't come off and the first time I only tried on a straight pin so now I think it's just a display -Pen on the table or something is kinda since the back is not removable :/ I'm disappointed I thought it was AMAZING.
