Lightweight Flat Lash Extensions for Fine & Sensitive Natural Lashes | Cashmere Classic 0.10mm

The lightest flat lash — a split-tip ellipse base that delivers a darker, more defined lash line than round 0.15mm classics at a fraction of the weight, ideal for fine, weak, or sensitive natural lashes.

Why You'll Love It

• Darker than round classics at lighter weight — the flat ellipse base creates more adhesive contact, so 0.10mm flat bonds stronger and looks darker than 0.15mm round at less weight
• Better retention for oily skin — more adhesive surface area means the bond is less likely to break down from oils or active lifestyles
• Split-tip finish — the natural split tip mimics real lash texture for a more natural, dimensional look
• Cashmere PBT fiber — ultra-soft, featherlight on natural lashes for all-day comfort
