These are so tiny that they are unusable. Can not use this product. It would be great for costume jewelry, fine jewelry the clasps are to small.

A good size for keychains or backpack clip-ons. Can even be used on jewelry for larger necklace pieces. Small and perfect for my use of clothing closures.

Good quality. Great packaging. Prompt delivery. Operated well. Would have liked a bit heavier duty but seem okay.
