• intros：{"brand_intro":"写乐（Sailor）是日本顶级钢笔品牌，创立于1911年，是日本最早的钢笔制造商。品牌以\"工匠精神\"著称，所有墨水均在广岛县自家工厂生产。写乐极黑墨水采用独家\"纳米碳素\"技术，颗粒直径仅为0.1微米，能完美适配超细笔尖。品牌在高端文具市场拥有极高声誉，其墨水被日本皇室和国会议员广泛使用。写乐的品控理念是\"零缺陷\"，每一瓶墨水都要经过人工目检和机器测试双重把关。","product_intro":"写乐极黑是品牌旗舰绘图墨水，定位\"顶级书写体验\"。核心卖点在于其极致的黑度（1.6以上）和顺滑度，能显著提升书写和绘画的质感。适用场景包括高端书法、漫画原稿、签名等。与百乐相比，写乐极黑的黑度更高，且流动性控制更好，几乎不洇纸。其纳米颗粒配方使墨水在纸上形成均匀的膜层，干燥后呈现哑光质感，视觉效果极佳。缺点是价格较高（50ml约65元），且防水性略逊于鲶鱼。","key_specs":{"容量":"50ml","颜色":"黑色","黑度值":"≥1.6","颗粒直径":"0.1微米","干燥时间":"约8秒（普通纸）","防水等级":"ISO 4级（良好）"}}
