What it is ｜ 产品说明
A “sandwich” dual nail form system designed with separate top and bottom molds to create precise builder-gel extensions with less filing and cleaner shapes.
The clear molds feature built-in guide lines and an ultra-thin full-nail design that hugs the nail bed, helping you extend, repair and sculpt salon-style nails faster and more consistently.
这款三明治甲膜是由顶模与底模组成的双层延长系统，通过上下夹合的方式帮助你快速完成延长甲，减少打磨时间，让胶体轮廓更干净利落。
甲膜为高透材质，带有长度定位线与整甲超薄设计，紧贴甲面，可用于延长、补甲与法式造型，帮助你轻松做出标准沙龙形状。
Texture & Application ｜ 结构与操作
Top and bottom molds fit together to sandwich builder gel, keeping product in place and guiding the ideal apex and length.
The ultra-thin edges and french-style back curve make it easier to pinch, align and remove without tugging the natural nail.
顶模与底模相互咬合，将胶体夹在中间固定成型，帮助自然形成理想弧度与长度。
整甲超薄与法式后缘设计，更容易卡住指芯并对齐，两侧机翼包覆指腹，脱模时不易扯伤真甲。

How to Use ｜ 使用方式
1. Prep the natural nail: push back cuticles, lightly buff and apply base as usual.
2. Choose a top and/or bottom mold size that slightly covers the sidewalls.
3. Method 1: Fill the top mold with builder gel, press onto the nail, cure, then remove the mold.
4. Method 2: Use top + bottom molds together as a sandwich – fill, align and clamp gently, cure, then remove molds.
5. Method 3: Use the bottom mold as a reusable form under the free edge to extend or repair broken nails.
6. Method 4: Take advantage of the French-style back edge on the bottom mold to sculpt clean French extensions.
7. Wipe dispersion layer, refine surface shape if needed, then apply color/top gel.
1. 做好甲面前置处理：推皮、轻磨、上底胶。
2. 选择略宽于甲侧壁的顶模/底模号数。
3. 用法一：在顶模内铺好延长胶，覆盖于甲面后照灯固化，脱膜即可。
4. 用法二：同时使用顶模+底模，上胶后上下夹合轻压，照灯固化后同时脱模。
5. 用法三：将底模卡在指芯下方，作为可重复使用的纸托替代，用于补断甲或延长。
6. 用法四：利用底模法式后缘弧度，在后缘位置铺胶，可轻松做出法式延长。
7. 擦除浮胶，如有需要稍作修型，上色胶或封层即可完成。
Pro Tips ｜ 专业技巧
Choose a size that fully covers the sidewalls for a tighter seal and less overflow.
Use the guide lines to keep every nail at a consistent length on both hands.
Apply a moderate amount of gel – too much can cause flooding when clamping the molds.
After removing the bottom mold, clean any tiny excess around the cuticle area with a fine file or buffer.
选号时以“刚好包住两侧甲壁”为准，这样更不易溢胶。
善用甲膜上的长度定位线，左右手延长长度更统一。
上胶不宜过多，夹合顶模/底模时如有溢胶，可用细笔稍作整理。
脱底模后，如边缘有少量毛边，可用细砂条轻修，整体无需大面积打磨。
