Sacred Ink - Black's
Adam Everett is the chief pharmacist, line pharmacist, and quality control person. He makes every single bottle of Sacred Ink to his exacting standards.
Sacred Ink tests for consistency, pigment load, and general quality. They color-match every single batch to ensure that each bottle of Sacred Ink is the exact same color as every other bottle.
Adam developed his ink recipe over decades, consulting with artists and clients to develop an ink that feels great to work with. Every bottle of Sacred Ink follows that recipe exactly, and it is hand-mixed by Adam himself.
