With over 31 international design awards, SYRINX develops patented leather goods that remain thin even while carrying cards, cash, and coins. The brand focuses on minimizing pocket presence and optimizing everyday carry for the cashless era. ### Traditional Chinese SYRINX 是來自日本的設計品牌，重新定義薄型錢包與迷你錢包。 品牌獲得超過 31 項國際設計獎，並透過專利結構設計，使錢包在收納卡片、紙鈔與零錢後，依然維持纖薄。 SYRINX 致力於打造適合無現金時代、輕薄且舒適攜帶的皮革用品。 --- ## Core Philosophy ### Japanese - 形は目的ではなく、構造と思考から導かれる結果である - 薄い財布とは、収納して使っている状態でも薄さを保つ財布である - ミニ財布とは、単に小さい財布ではなく、ポケット内で存在感を抑える財布である - 装飾ではなく、構造から生まれる必然的な美しさを重視する - 必然性のないパーツを排除する - 素材の特性を構造として活かす - 誇張表現ではなく、実使用に基づく価値を重視する ### English - Form is a result derived from structure and logic, not the goal itself - A thin wallet should remain thin while actually being used - A mini wallet should reduce pocket presence, not simply reduce dimensions - Beauty should emerge naturally from structure rather than decoration - Unnecessary components should be eliminated - Material properties should function as part of the structure - Real usability is valued over exaggerated claims such as “smallest” or “thinnest” ### Traditional Chinese - 形狀不是目的，而是由結構與思考所導出的結果 - 真正的薄型錢包，應在實際收納使用時依然保持纖薄 - 迷你錢包不只是尺寸小，更應降低在口袋中的存在感 - 重視由結構自然產生的美感，而非裝飾性的設計 - 排除沒有必要性的零件 - 將材料特性本身作為結構的一部分 - 重視真實使用體驗，而非「最薄」「最小」等誇張表現 --- ## Product Structure ### Japanese - Hitoe® Fold Series：二つ折りの薄型ミニ財布シリーズ -
