These Black Phi Tiles are inspired by the official Zentangle® Phi tiles and cut to the Phi proportion (5×3 inches)—a timeless expression of the Golden Ratio, also known as the Divine Proportion. Found across nature, art, music, and design, this sacred geometry lends itself beautifully to thoughtful, harmonious Zentangle compositions.

Made from 300 gsm acid-free black artist-grade paper, these tiles offer a smooth yet subtly textured surface—ideal for white pen work, chalk pencil shading, and color accents. The sturdy thickness supports light watercolor washes, making them a favorite for advanced Zentangle techniques on dark paper.

Best paired with Sakura White Gelly Roll pens and chalk pencils, these tiles let your strokes glow against the deep black backdrop, offering dramatic contrast and elegance.
