The Story of the Form

The Official Hat family is recognized for its wide shoulder structure and upright, dignified silhouette.

This example takes that architecture further with a larger body and naturally concave base. The recessed foundation changes the way the shell sits in the hand while also giving the walnut a more sculptural profile when viewed from below.

At 45mm, the pair has noticeably strong visual presence. The broad shoulders frame a deeply textured center, while the pointed crown maintains the characteristic vertical tension of the form.

Rather than appearing overly symmetrical or manufactured, the pair retains the irregular folds, cavities, and ridge variation expected from naturally grown Wenwan walnuts.

Product Characteristics

Large 45mm Body
The substantial width gives the pair a strong collector presence without becoming excessively tall.

Broad Official Hat Shoulders
Wide outer shoulders create the classic Guan Mao silhouette and make the pair appear especially full from the front.

Concave Base Structure
The recessed base gives the walnuts additional depth and a distinctive lower profile.

Deep Central Texture
Dense folds, cavities, and raised ridges create strong contrast across the face.

Balanced Natural Pairing
Both walnuts share similar overall dimensions and architecture while retaining their individual natural details.

Care

Keep the walnuts dry and avoid sudden changes in temperature or humidity.

Use a clean Wenwan brush regularly to remove dust from the deeper recesses. The central cavities on this pair are relatively deep, so consistent brushing will help maintain an even surface appearance.

Avoid soaking, chemical cleaners, and excessive oiling. Natural handling and regular brushing are recommended for gradual patina development.
