The kind of wood used to make a wooden box depends on the purpose of the box. For example, when placing light-colored cotton, polyester and silk fabrics, it is not advisable to use camphor wood and pine wood (which will make the fabric color yellow), but it is advisable to use Fraxinus mandshurica, Fraxinus mandshurica, Chinese fir, phoenix tree (but the structure of phoenix tree is relatively thick), elm (but it is too heavy to carry) and birch. Wool clothes should use camphor wood and nanmu. If food, rice and noodles are served, camphor wood, nanmu, Chinese fir and pine are especially unsuitable, because their woody taste is too strong, which will "rob" the normal taste of food; If elm is "stuffy", it will also produce an unpleasant smell. If you put books, except pine (pine oil pollution), the above categories are suitable. In addition, the Cyclobalanopsis glauca wood you mentioned naturally has a sour smell, and the texture is too hard and heavy, which is difficult to process and easy to crack. It is recommended not to use it.
Last but not least, all kinds of wood must be thoroughly dried (moisture content: less than 0/5% in the south and 0/0% in the north). Otherwise, even if the box is finished, it will inevitably crack or deform in the future, which will "suffocate" your book.
