• ② 100% Remy Human Hair: Crafted from cuticle-aligned Remy human hair, these 30-50g extensions blend seamlessly with fine or thick hair. Heat-friendly up to 250°F - straighten, curl, or style freely without compromising silky texture.
• ③ Petal-Shaped Comfort System: The medical-grade injected tape adhesive with central ventilation channel ensures secure 4cm grip. Weight-distributed design prevents scalp tension. Ideal for sensitive skin - stays invisible under windy conditions.
• ④ 5 Sizes for Custom Volume: 14"-22" lengths (30-50g/pack) with sandwich installation guide. 1 pack adds subtle layers; 4 packs create dramatic fullness. Includes temple-specific micro-wefts for edge detailing.
