Phor Prai B.E.2544 amulets were made by the Foundation of Luang Phor Tim Issarigo, in B.E.2544.
Mr. Chinaporn Suksatit, the chairman of the team, contributed as many as 2,000 old wrecked Phra Kring Chinabanchorn amulets as the base for the sacred mix.
All the Phra kring Chinabunchorn amulets were created by Ajahn Sakorn, the abbot of Wat Nongkrub, a close follower of Luang Phor Tim.
The original Phra Kring Chinabanchorn amulets were created on five Saturdays and five Tuesdays, believed to be holy days on which to create sacred amulets. As such it is believed that this would assist the transference of a high degree of sacred power into the new Phor Prai amulets.
Furthermore Luang Phor Sakorn and Luang Phor Phromma, another famous Thai monk recited the sacred incantations to bless these amulets.
These amulets are now quite rare, as they were consecrated almost 8 years ago.
