This is the "Onyx" model from Willie's (Willies) Jewelry series, a signature model by Yu Tamaki. I'm selling it to organize my equipment, hoping someone can make good use of it. The concept is to add a symphonic quality to the transparency of Crystal. My impression after using it was that it allows Japanese players to effortlessly achieve a Greg-like symphonic sound. Condition: As shown in the photos, there are no noticeable scratches or dents. Rim and cup interior: In good condition, with no scratches. Shank: There are some scuffs from insertion, but no distortion. Overall, I think it's in good condition with little use. There is no damage that would affect playing.
