EC Exclusive Pattern B Popular for its easy-to-write-on, non-bleeding ring-bound design. This is a standard Delfonics notebook that combines a "simple, timeless design" with "ease of use." It has a thick cover that makes it easy to write even while standing. It uses high-quality 5mm grid paper that prevents ink from bleeding through. All pages are perforated, making it easy to hand over notes to others. A clear pocket is also included at the end. I purchased this as part of a collection and have kept it unopened. I would like to sell it here to organize my collection.
