FIBO STEELFIBO STEEL 4mm Stainless Steel Rope Chain Necklace for Men 16-30 inches Silver Gold Black-tone

Q: Does it make my neck itch

Doesn't make mine itch. And I only take it off to shower. I workout in it and run and everything else. No rashes or irritation at all for me. Doesn't bother me one bit

Q: Are there any stainless steel pendant for men that would fit this necklace?

I'm sure there are a bunch. I have a silver pendant of a bear that I wear on mine... As long as the claw clasp fits through the ring that the pendant hangs from, you are good to go.
