After receiving Wenwan Walnuts, it is recommended to store them for a few days before playing with them. Because there will be temperature difference issues. Express delivery from one place to another, especially in winter, from outdoors to indoors. Although the walnuts shipped by the seller are sealed in airtight bags, it is best to leave them for a period of time.

In addition, some walnuts may not have completely shrunk (dried in the shade), and it is more beneficial to leave them for a period of time.

According to my experience in playing with walnuts, it is best to use a wire brush to prime new walnuts (to speed up friction to remove the roughness on the surface of the walnuts), then change to a bristle brush and continue brushing for a period of time, and let it sit for half a month. I'll start playing hand-to-hand in a month. In the process of playing, it is also necessary to use the nano brush for polishing. In this way, the walnuts played later will be more translucent.
