I needed a good magnetic closure for my mom...made her a few items at Christmas and she is no longer able to manipulate a lobster claw closure so these fit the bill. Good tight closure as well.
They don't work for me....;o(
I have about 20 of them, but I have yet find a Jump Ring that will fit the opening on the mag-lok. They just won't go in the hole...it's too small. No directions ever given as to what kind of jump ring or split ring will fit.
This clasp is not going to come apart on you! I was looking for a replacement clasp to a decorative, but not very effective, magnetic clasp. This clasp, while not decorative, did the trick. The look is simple enough that it does not detract from the design of the jewelry. Be warned however, one of my customers informed me that the magnet caused her watch to lose 10 minutes. I am downgrading her clasp for this reason.
When I ordered these, I thought they would be wonderful for the 'heavier than usual' necklace, bracelet and earrings set I was stitching. Upon applying the clasp to the necklace and putting it on for trial - I found that it holds SO WELL that I had to take my pliers (two sets) to separate the two parts of the clasp. If one could deal with that, I would recommend these for any of your heavier projects. If you have a weaker than usual grip, a different type of clasp would be best for you.
WORKS WELL, DIFFICULT TO 'UN-CLASP"!
