Product Description
Model LJV-AC-ST is a premium A-Class student period panty engineered specifically for young women navigating academics, activities, and adolescence. "A-Class" refers to GB 18401-2010 Class A — the highest grade of fabric certification under China's national textile safety standard, ensuring zero harmful chemical residues, hypoallergenic materials, skin-safe dye processes, and testing for skin irritation. This is particularly important for products worn next to sensitive skin.
The 95% Cotton / 5% Spandex body provides natural comfort, temperature regulation, and superior moisture absorption — the highest cotton content of any teen product. The 100% pure cotton lining is gentle on sensitive skin during long wear. The 4-layer system (quick-dry top + absorbent core + waterproof membrane + cotton comfort bottom) holds 15-20ml for light to medium flow, with 6-8 hours of wear time per use.
Designed specifically for school: mid-rise brief fits under uniform pants and skirts; neutral colors (White, Nude, Light Pink, Light Blue) work with all uniforms; no VPL under skirts or pants; tag-free for comfort; stays in place during PE and after-school activities. Independence-friendly care: simple machine wash cold, air dry.
Suitable for: first periods, light to medium flow days, school days, standardized testing, sports, commuting, overnight stays, and as backup with tampons or cups. Recommended: minimum 3-4 pairs for rotation. Service life: 2-3 years with proper care.
Special pricing available for: schools, educational institutions, school health programs, bulk orders over 500 pcs, repeat orders, annual contracts, and non-profit organizations.
