The Design

About Ringo Gamaguchi کیف پول قفل‌دار

این محصول شکل یک سیب را به خود گرفته است، زیرا از رینگو تکس ساخته شده؛ چرمی مصنوعی که از ضایعات سیب به دست می‌آید. ابعاد آن بر اساس اندازه یک سیب کوچک واقعی طراحی شده تا بر منشأ آن تأکید کند. ویژگی اصلی آن باریک بودنش است که معمولاً در میان کیف‌های پول قفل‌دار دیده نمی‌شود. این امر با به‌کارگیری روش دوختی متفاوت از کیف‌های پول معمول حاصل شده که به ساختار اجازه می‌دهد نازک باقی بماند. هدف، خلق محصولی بوده که به‌راحتی در کیف‌ها یا جیب‌ها جای می‌گیرد و امکان حمل هوشمندانه سکه‌ها و دیگر اقلام کوچک را بدون افزودن حجم زیاد فراهم می‌کند.

Unique Properties
This clasp purse utilizes "Ringo-Tex" a bio-based leather developed by appcycle Inc. in Aomori, Japan's largest apple producing region. Around 20,000 tons of apple residue is produced each year, much of it discarded or incinerated, contributing to CO2 emissions. Ringo-Tex upcycles this waste into synthetic leather through a low-carbon stabilization process. Molded into a 3D apple form expressing it's origin uniting symbolism and craftsmanship while inviting participation in a sustainable society.

Production Technology
The product is built from four key materials: a clasp frame, Ringo-Tex bio-based leather, an electroformed nameplate, and lining. While the clasp is standard, molding Ringo-Tex is far more demanding than working with genuine leather and required six months of research. Stitching along the complex contours demonstrates Japanese craftsmanship. The gold seed motif, mass-produced by molding, defines the brand’s elegant identity.
Design Challenge
The greatest challenge in developing this product was achieving the bumpy texture and stitching applied to complement it. While embossing genuine leather is relatively easy due to it’s elasticity, plant-based synthetic leather is difficult to shape and sew because it lacks these properties. After six months of collaboration with multiple companies and testing we succeeded in creating the texture using a proprietary welder process. It is the product’s most charming yet challenging feature.
Research
Ringo-Tex is created by processing apple residue into power and using it as a raw material, reducing petroleum-based inputs in manufacturing by 72 - 74%. This approach lowers the dependence on finite fossil resources and decreases environmental impact. It maintains the durability and water resistance comparable to existing synthetic leather, offering a upcycled next-generation bio-based material that balances sustainability with practical performance.
Inspiration
This product is the first release of "Golden Seed" a brand created to embody appcycle's philosophy of "circulation". With the concept of "sowing regenerative seeds and facing a golden future" it expresses Aomori's identity it's apples in a cute, friendly, and accessible way. With refined construction intricate and meticulous stitching reflect the depth of Japanese craftsmanship.
Project Duration
The Project was started in 2025 Aomori and was unveiled in Tokyo in January 2026 as the debut product of the Golden Seed brand. For the next phase the team plans to launch a crowdfunding campaign followed by expansion into online platforms and retail stores both in Japan and internationally.
Operation Flow
A clasp purse with a push lock to store and carry small items such as coins, AirTags and SD cards.
