Please see my other listing for the introduction of Wenwan walnuts and the terminology of Wenwan walnuts. Beware of carved/trimmed walnuts. You may ask why, because tons of walnuts off the tree each August, and you still can not find a 100% natural un-carved pair? If you're ok for a carved/trimmed pair, why not just grab a black walnut, it's everywhere, and can carve whatever you like. A carved/trimmed pair can cause different color over the years of handling, also it maybe a flaw pair. Please always ask for a detail zoom-in pic, Wenwan Walnuts should be considered pair by pair. Otherwise it's no difference from a edible walnut.
