This is just right for the more dainty necklace c-ring clasps. Very easy to use and easy to fasten your necklaces or bracelets. I like the ease of use and that it was dainy enough for a smaller sized bracelet i am using it on.

The magnetic clasp makes dressing up my outfits sooo much easier. This magnetic converter is a godsend! This is very sturdy and the magnets are strong.

The spring ring clasp is very small and i can't seem to get it on the chain without the spring ring sticking to the magnet part. Don't recommend for fine, delicate necklaces.

The smaller, flat shapes are comfortable and look appropriate on fine jewelry. The pieces are quite attractive as well. They are a much better price than i could get at the craft store.
