I use to live in SEA too... n have two Bal bracelets. Nothing hasn't ever happened to them. Haha I even get water on them when washing hands and sweat while driving in the humidity. You should go for it and just try one out. You might be hooked! Hahaha ... just sayin'Im in SEA, tropical climate with high humidity. To have leather contact with the skin most of the day is "risky" to me as i perspire easily. Off course im sure it's workable to many others residing in SEA. It's just ME, who don't have the courage to try it![]()
