This is a larger, heavier version of the Yeop Chagi pendant, more appropriate for the thicker chains that men typically wear. In the right materials (such as polished bronze) this would also look good on a leather cord.
"Why is this so expensive?" There's actually not a lot of markup on this item -- the cost is in all the metal that's used. Compared to my other pendants, this one uses a lot more metal. This is a very substantial piece that would look very good on larger men.
