There are two commonly used thicknesses, 80 grams, and 100 grams. In fact, the gram does not represent the thickness of the paper, but the density of the paper. In order to understand it, it is convenient for everyone to understand it literally. 80 grams of paper, slightly thinner than 100 grams of paper, is about the same thickness as our usual writing paper. Both kinds of paper can be used for inner pages, the difference is that 80 grams of paper, because it is thinner, the strokes will be softer, and the feeling of writing will be more comfortable. And 100 grams of paper is more rigid, and the writing feeling is not as good as 80 grams, but it looks high-end, and each has its own advantages.

Beige Dowling paper, very soft in color, is the first choice for inner pages for those who like to write. Pure white paper, white is irritating to human eyes under strong light, and looking at the white paper for a long time will make eyes tired and easy to shed tears.

The smoothness of paper writing is very important, which is very important to the process of making paper (gluing), the surface of good paper must be smooth and flat, and the writing is smooth. The paper is of low quality, writing with an astringent feeling, and the paper has more noise.
