These hooks are the greatest find. They are vintage and made of Lucite. Each hook measures 1-3/8 inch by 5/8 inch. you can hook them together in many ways, or use them separately. They're great for plastic and Lucite necklaces or even larger metal chain. They make great clasps for other loops and hooks, too.
The variegated colors in these hooks is quite interesting. they run from pink to black - but they are predominantly pink. We're not sure what the plan was when making this color, but it came out pretty cool indeed. Two pairs of hooks are shown to illustrate their versatility.
