Buying Guide

Match curl to natural bottom lash

Choose C or D curl options depending on how much lift you need—C curl gives a subtle lift while D curl creates a more dramatic outward flare

Pick appropriate diameter

Select thinner diameters (0.03–0.05 mm) for lightweight, safe attachments on delicate bottom lashes; 0.15 mm is thicker and better for stronger natural lashes or cluster styling

Choose lengths for natural look

Use shorter lengths (9–12 mm) for a natural, flattering bottom-lash effect and longer lengths (13–15 mm) when aiming for a more stylized finish

Consider material and finish

PBT synthetic lashes and faux-mink tags indicate durability and a matte-black or soft finish that blends well with natural bottom lashes

Buy multi-length trays for flexibility

Multi-length sets (multiple mm per tray) let you mix lengths across the lower lash line for a tailored, tapered look and better value per tray
