I bought it for my wife as a gift. When she opened it up, I used the tools that came with it to remove two of the links to better fit her hand. I used to work in the jewelry store and had no problem removing and replacing links. After a day of normal wear, one of the pins fell out. I replaced the needle and the next time she put it on two needles fell out. Wrote the seller, got no reply. I do not recommend this.
