I have just ordered the comfort back Le Disc Plus from you..what a delight to find your site!  I recently got a second piercing and have a lot of new studs to use. One pair of expensive diamonds. I have found the tiny butterfly backs impossible to use and they are causing a lot of frustration..easy to lose.. and annoying to try to get them on. I was looking for an alternative and there you were online.  I am looking forward to receiving these backs and now can wear my new earrings.
