💎【Prototype】Fortuna Pearl 21mm Width: Original Bag with Luster and Geometric Patterns

こThis piece is a prototype luxuriously crafted using "Fortuna Pearl (21mm width)," a material characterized by its silky smooth texture and elegant, pearl-like luster.
The main body is expressed through intricate and complex geometric patterns—such as diamond lattice, harlequin check, and diagonal check (Ichimatsu check)—maximizing the beautiful texture of the material.

🌟 Design and Unique Innovations

【Body Design】

Material: Fortuna Pearl 21mm width
Size: Designed with 10 squares wide (W) × 5 squares deep (D) × 12 squares high (H). The dimensions utilize the 21mm width material to create a significant presence.
Design: The glossy material ensures the geometric patterns display various expressions depending on the reflection of light.

【Innovative Original Handle】

This handle is an original specification by "Handicrafts Store☆ALAUDAE," full of unique ideas.
Weaving Technique: Woven using 12 strands of Fortuna Pearl 4mm width.
Unique Innovation: Innovative and unprecedented ideas, such as weaving the handle onto a tube, have been adopted.
Specifications: Total length of 42 cm. It is secured with rivets at 8 points, but the rivet attachment points are concealed with decoration, demonstrating a commitment to detail and enhancing the design aesthetic.

The Fully Realized Form: The Challenge of Prototype Nana (Seven) 12-Mass

Since "Pearl Prototype 1," I have manufactured "Prototypes 1–4," but each one had minor flaws and difficulties, leaving me personally unsatisfied with the finish. Therefore, for this Prototype Nana (Seven) series, I fundamentally reviewed and corrected the knitting chart to solve those past issues, finally completing this prototype.

Weaving Lessons and Progress

The method previously attempted with "Pearl Prototype 4"—deciding the material length first, starting the weave from the inner base, folding over at the vertical top, and neatly finishing the outer base—was efficient. However, with this method, it was impossible to achieve a perfect *Ichimatsu* (checkerboard) or rhombus pattern beautifully on both the inner and outer surfaces of the base.
While methods like the partial material addition of "Pearl Prototypes 1–2" are possible, I determined that this offered no technical advancement and would not result in a sellable product. Thus, I prioritized perfection and did not adopt that method this time.

Handle: Shortest in the Series and Functional Design

The handle parts utilize the 12-strand round braid method established in "Pearl Prototypes 5–6." Notably, a cold-resistant tube capable of withstanding temperatures down to -10°C was incorporated as the core to ensure the bag can be used year-round, even in winter.
This handle is thicker than those on the "Prototype Nana 6-Mass and 9-Mass," and its length is 30cm, making it the shortest handle in the "Prototype Nana Series."

Decoration Reflecting Environmental Consideration

The technique of covering the double-sided rivet (hardware) parts with a decoration made of "Fortuna Material" is more than just ornamental. It is an idea to "not waste material" by not discarding remnant scraps, but rather joining them to widen them or transforming them into narrow string-like forms for reuse. This also demonstrates consideration for the plastic waste issue.。

Excellent Durability and Maintainability

All materials other than the brass rivet are composed of 100% Polypropylene and PVC. Therefore, if the bag gets dirty, it can be directly washed with water or wiped with alcohol disinfectant. I am confident in its durability, barring exceptionally rough handling.
総The total weight is approximately 696g. It is difficult to judge whether this is light or heavy for this size. However, considering the ease with which one can enjoy a step-up in style and, more importantly, the extremely durable construction, I believe the weight is reasonable.

Future Verification Plan

The Prototype Nana Series ("Prototype Nana 6-Mass, 9-Mass, and 12-Mass") produced this time will not be sold. For promotional purposes, the administrator and their family will use them daily, directly checking the durability and any defects. They plan to report their usage experience on web blogs, utilizing the feedback for future product development.
