Phra Phrom (Four-Face Buddha)

Recently, I have been really interested in amulets, and began to browse different variants of them. I see that majority of the amulets’ marketplace (or at least popularity impression) fills with either Somdej, Pidta, LP Tuad Butterfly; and I rarely see Phra Phrom being worn as amulet.

Is there a reason why so?

Thanks!

**EDIT: I am genuinely interested in understanding why Phra Phrom was not well marketed as amulets as compared to other variants, given that divinity rank is superior. I am intending to get one for myself…**
