Founded in 2020 with a simple and straightforward initiative to create jewelry for personal enjoyment, bound by oath has evolved into a brand specifically catering to gentlemen.
"Chawapat Soisiri (Phukao)" and "Rattanarawin Soisiri (Knomhwan)" are no strangers to the jewelry industry. The brand was inspired by Phukao’s aunt, "Khun Ying (a Thai noble title equivalent to "Lady") Suneerat Soisiri", whose deep appreciation for fine craftsmanship led her to establish a small jewelry factory with skilled artisans, initially catering to court officials and royal officers.
