The notebook pages are designed with the BioGeometry "L90" and "Brain Shapes" to create a BG3 emission across the whole page. The L90 shape is notable for its centering effect on the body's emotional and mental levels and the Brain Shapes for their synergistic effect in harmonizing left and right brain functions by connecting them to BG3. Each set of three notebooks contains one plain, one lined, and one dotted notebook.
