I am a fat man, and I want to buy an obsidian bracelet, wrist circumference 19.6. I want to ask whether the bead diameter is 16mm or 18mm, because I can't find it online.

Beads with bead diameter 18mm are larger. If you like oversized beads, you can choose 18mm. I like something low-key, and the beads are smaller. You can choose bead diameter 16mm and wrist circumference19.6cm. You can make a hair that suits you according to your wrist circumference, and you can also give you spare ropes and beads in case it doesn't fit.

Obsidian has a good effect of absorbing negative energy. I hope I can bring good luck to you and your family!

I hope you can be satisfied with the reply! I also hope to get everyone's support, Hengtai Fengshui flagship store.
