clasp size is perfect, very easy to open and close. the thickness is great and the extender is very comfortable. i've been wearing for a while now & it hasn't started to tarnish at all.

These are so easy to use. I love being able to adjust as needed my necklaces!!!

Doesn't tarnish!!! Literally so hard to find jewelry that actually doesn't tarnish like the company claims. These tell the truth. I have worn a necklace with one of these extenders for 3 weeks now 24/7 — showers, working out, sauna — and they are as good as new. Highly recommend.

These necklace extenders work perfectly! When you buy a necklace online the chain length is usually 18 inches which is too tight for my neck. These extenders allow me to buy a necklace I love and wear it comfortably. They are sturdy and I love the three different sizes. Highly recommend!

I really like these; the multiple length options are extremely convenient. So far they have not tarnished and I have had them for a couple of weeks. I've been wearing them every day, even at night and in the shower sometimes. They are thick and very functional.

This product exceeded all my expectations, and I would definitely recommend it.

Just what I was looking for to be able to wear 3 necklaces that were all nearly the same length. Pleased with the quality.

The best combo for layering. Very high quality. I used this for the gym and the materials still intact. Great gold color, looks like real gold. The 3 sizes are longer than I expected. I use daily and you can wear 24/7. The extensions are weightless.
