Official Hat “Turtle-Back” Wenwan Walnut Pair — 42.0mm x 38.0mm | GMZF-401E

A distinctive Official Hat Wenwan walnut pair with a naturally developed turtle-back profile. Measuring 42.0mm x 38.0mm, the pair combines generous width with a lower, broad-backed structure, giving the walnuts a strong, settled presence and a compact domed silhouette.

The most recognizable feature is the arched upper body and layered ridge structure, which create the shell-like appearance collectors describe as “Turtle-Back”. The name refers only to the natural visual form of the walnuts; they have not been carved or reshaped to create this look.

Both walnuts show similar proportions, ridge flow, body fullness, and warm shell tone. Displayed together, they present a balanced, grounded appearance with the broad horizontal spread that is especially attractive in this form.

This is a one-of-one listing. The pair shown in the photographs is the pair you will receive.

The Story of the Form

Official Hat walnuts are appreciated for their balanced structure, defined edges, and composed overall silhouette. In this pair, that structure develops into a more unusual turtle-back formation.

Each walnut has a broad upper body with layered ridges that spread outward and downward, creating the impression of a domed shell resting on a compact base. The ridge line runs firmly across the middle, visually dividing the top and bottom sections and reinforcing the pair’s stable, grounded stance.

The turtle-back character is especially appealing because it combines width, symmetry, and sculptural depth. These two walnuts are also well matched in body volume, ridge height, texture density, and shell color, while still preserving the natural individuality expected from genuine Wenwan shells.

Product Characteristics

• Distinctive turtle-back profile: Broad domed upper bodies create a shell-like appearance.
• Official Hat structure: Strong natural ridge development and a stable overall silhouette remain clearly visible.
• Generous proportions: At 42.0mm x 38.0mm, the pair has a fuller, more substantial presence.
• Layered natural texture: Folded surfaces and recessed grooves create depth throughout both walnuts.
• Balanced pairing: Both walnuts show similar width, body fullness, ridge placement, and shell tone.
• Natural, unmodified form: The turtle-back appearance developed naturally and has not been carved or altered.

Care

These walnuts have already been pre-cleaned and base-brushed. During the first month, store them in a sealed bag when they are not being handled, allowing them to acclimatize gradually to your environment.

Handle them with clean, dry, bare hands and brush the grooves gently with a clean, dry walnut brush. Pay extra attention to the recessed channels around the central ridge and lower texture, where dust can naturally collect.

Keep them away from water, oil, direct heat, and prolonged sunlight.
