Luang Pu Khampan Khosàpanyo
I have limited information on this Somdej as it rarely surface in market. Also quite a limited batch. But judging from it's ingredients used, I definitely love it.
Pong Pai Dam isn't Prai. Luang Pu Khampan has not Prai ingredient.
This is the Silver takrut embedded version
Somdej gives all round blessings or Putthakun. Protection, brings up luck, Metta etc.
And from renowned names like Luang Pu Khampan, there ain't room for doubt.
