This was a great value for vivienne westwood sale set of necklace extenders! I looked other places and I could get 1 extender for the price I paid for 5! I like the fact that I can leave the extender on the necklace rather than having to take it off everytime.These were a well needed item vivienne westwood my jewelry armoire. They have worked beautifully with most of my necklaces. The only challenges I've had were on necklace clasps that have a skinny oval shape. The round clasps on the extenders ends are too big to fit through the ovals. Needless to say they rest right where the lever piece goes in and out of the clasp.I bought vivienne westwood uk for my mom for Mother's Day because she loves butterflies and the color purple. The price is a steal for a necklace such as this, but soon after I ordered it I looked at other pictures of this product. It is a really small pendant.
