Hardware is great, the pliers are okay (i don't really use them, i have a table rivet press i use). The only complaint i have is that each key fob is individually wrapped in it's own small plastic zip bag.
But perfect for tags, or beads, or light straps. They work great for my resin pieces.
Of a deal. Price is affordable, and so far, i haven't had one break. Quality is good, snap hook is good.
The spring is strong and works well -- no worries about the clasp springing open. The swivel works freely and there are no sharp edges or points to cause problems.
These clasps are exactly what i needed. For my purpose they work beautifully so far. They are the perfect size and are well made. That makes them a bit harder to install but the end product is much better.
