• intros：{"brand_intro":"写乐（Sailor）创立于1911年，是日本历史最悠久的钢笔品牌之一，被誉为\"日本钢笔之父\"。写乐在墨水领域同样拥有深厚积淀，其极黑墨水是品牌技术实力的巅峰之作。写乐坚持\"匠人精神\"，所有墨水均在广岛工厂手工调配，采用纳米级碳素颗粒技术，在保持极致黑度的同时解决了传统碳素墨水的堵笔问题。写乐墨水在高端书写圈中享有\"黑中之黑\"的美誉，是许多书法家和设计师的御用墨水。","product_intro":"写乐极黑是品牌旗舰级墨水，定位为专业书法与艺术创作墨水。50ml容量，主打\"纳米碳素\"技术，颗粒直径仅为传统碳素的1/10，既保证了极致的黑度与光泽，又不会堵塞钢笔毛细。核心卖点在于其独特的\"镜面黑\"效果——干后呈现金属般的光泽，在灯光下极具质感。适合书法创作、漫画勾线、签名等对黑度要求极高的场景。相比鲶鱼永恒黑，写乐极黑在流动性上更优，且气味更小。","key_specs":{"容量":"50ml，精致瓶装","墨水类型":"纳米碳素墨水，高黑度、不堵笔","颜色":"极黑（带镜面光泽）","适配笔型":"适配所有钢笔，尤其适合细尖笔","干燥时间":"约15-20秒（普通纸）","包装":"玻璃瓶装，瓶身有写乐标志性船锚logo"}}
