Phi Ruler x TATOU Golden Ratio Sketch Book Kit Set: Overview
Phi Ruler x TATOU Golden Ratio Sketch Book Kit Set helps creators sketch balanced ideas on paper, at a desk or on the move.
- Golden ratio grid pages: The first 93 pages include printed grid lines based on golden rectangles, so sketches start with clear proportion and cleaner layout.
- Copper Phi Ruler: The laser-etched ruler helps draw golden circles, spirals, curves, straight lines, and perspective guides, so one tool supports many drawing tasks.
- Pen-friendly paper: The 80 gsm FSC certified acid-free paper works with pencils, pens, and fountain pens, helping reduce bleed-through and feathering.
- Lay-flat TATOU notebook: The 180° opening keeps pages steady while you draw, while page numbers, contents pages, bookmarks, and an inner pocket keep work organized.
- Portable kit design: The ruler and notebook work together, making golden ratio practice easier for designers, architects, illustrators, and daily sketchers.
It is a practical kit for learning proportion, planning concepts, and keeping sketch work organized anywhere.
