Pros : The cross is a good size for the really small scrap and chips I tend to get as jewelry off-cuttings and large enough it doesn't feel like it will snap as a necklace.
Cons : The post on the one I got was really weak. I used ZYP and sprayed from every angle, but I still lost the post on the second use. It came out of the finished piece, but it didn't stay attached to the mold....
I've just been wrapping a piece of nickel chromium alum wire with fiber paper and putting it in the hole of the first one. That works okay, but I still have to clean up the hole and I'm always concerned the jury rigged set up will fail and it will leak.
Other Thoughts : The original hole ends up so big that it kinda throws off the balance, I actually like my jury rigged version better when it comes to size because I can keep that to a smaller, round hole that I put a finding through. But I'm still considering getting another one in the hopes that it's not so weak.
