The BLU Notebook is the first ever writing journal made from pages that have the look and feel of traditional blueprint paper. The books are used with opaque white or bright coloured gel or paint ink. BLU offers an aesthetically pleasing effect when using vibrantly pigmented white and coloured gel ink against the rich blue pages of BLU. BLU is versatile, containing 50 pages of high-quality blueprint paper with tear sheets to etch out all your ideas. And, to withstand the daily grind, BLU has a strong front and back cardboard cover. The blue paper contains a light blue grid that is subtle enough to not distract from written notes, as is the case with some drafting paper containing darker grids. The BLU Notebook grid is a 1/10th" light grid within a bolder 1/2" grid, permitting multiple scaling references. Printed using FSC & SFI Certified Acid Free paper.
