The necklace fastens with ease. The magnetic extender has a clever design that clicks into place. The package includes four clasps, two silver, two gold.

All of the clasps work properly and none of them are misaligned. Great for inside keychain in bags. Worked perfect for my hand sanitizer holder.

Exactly as advertised well pkgd and fair price. Excellent quality and flawless function. Very good product,very fast shipping.

The lobster claw portion of this clasp is only for light duty applications. Would probably be good for a keychain or something like that, light duty. Instead they send me a retractable id holder?
