Thai Buddhist Nam Mön holy water from the 108 temples of Wat Hong Rathanaram.
Wat Hong Rathanaram houses the largest holy water pool Nam Mön
from Thailand (45 meters long!),
This basin was founded on a sacred spring by the first King of Thailand
and has been maintained and used for over 200 years. 
Once a month, a grand ceremony is held and blessed water from 108 temples is collected and poured into the King Thaksin Fountain.
The bottom of this fountain is composed of several plates decorated with powerful incantations and pentacles intended to charge the water that circulates there. (see photo) 
Many people with Sak-yant tattoos take advantage of it
to come and “recharge” their tattoos with this water.
This is one of the possible uses of this special blessed water.
This Nam Mön blessed water is undoubtedly the most powerful
that you can hope to obtain,
It is presented in a beautiful glass bottle decorated with gold leaf.
