This back-to-back notebook features 140 blank pages of acid-free cream paper on one side; turn it over to find 140 narrow-ruled (6 mm) pages on the reverse. Both wire-bound notebooks measure just over 3 × 5¼ inches. Whether you need to draw up a quick plan or write out a few ideas, this pocketable, wire-bound, two-in-one notebook has you covered. Flip open the drawing side, the writing side, or both at once.
