These are not edible walnuts. They are mountain walnuts created by nature. They are much harder than edible walnuts. For play walnuts, a deep texture with striped patterns is necessary. Also, it is important that the patterns are similar, the size is consistent, and the weight is about the same. Therefore, a huge amount of work time is spent to create a pair of play walnuts. No varnish is applied! They are 100% natural walnuts! You can bring out the shine by brushing them. The Guanmao walnut (Qilin pattern) looks like the pattern of a Qilin. It is one of the popular types of walnuts. With Wenwan walnuts, the more you play with them, the more they shine and the more character they develop. After holding them for months, the color will begin to deepen and change. Eventually, they will become as beautiful as rubies. I hope you enjoy the changes. Thank you! Please refrain from purchasing if you are looking for perfection, as these are made by nature!
