This piece turned out great

This piece turned out great—I love the pendant’s double‑sided design. With the new season of *Black Clover* coming soon, I’m ready to rock my Black Bulls pendant, and I appreciate its quality, weight, and overall feel.

Came as advertised, looks like its ripped straight from the game itself, only issue is the size but that was an issue with my conversion from UK to US ring sizes, so triple check if your needing to convert from one size to another.

I absolutely loved the pendant!

I absolutely loved the pendant! I chose the Crest of Courage, and the detail is incredible—especially in the 18k gold vermeil option. You can really see the craftsmanship. I’ll definitely be buying again!

I love it, highly recommended!

First things first, while the biggest option they offer is nowhere near as big as it looks in the picture, it's actually a perfect size in person. All the details are sharp! I chose the "Antique Silver" which gives certain areas a rough and darker surface, It's not everywhere but I think it's for the best. It's my new favorite pendant!
Edit: Don't forget to add the chain to cart, it does need to be added separately. I totally missed that when ordering, Kaiworks was awesome enough to send one after getting in touch with them.
