Luang Pu Up Khemajaro
This is the official 3rd Batch (Phim Yod Nam) of Wat Thongsai.
Known as "Phim Yod Nam" or waterdrop mould.
What's you're paying for is a Genuine Mae Phim of Luang Pu and the actual recognisable handwritten Yant "Uù Gà Pà Sà Hà Nà Pud" by Luang Pu Up Himself.
These days, real handwritten Yant of Luang Pu is like treasure if found.
