Model 9039 is Ljvogues' most accessible period underwear—a straightforward, reliable 3-layer leakproof menstrual brief built on a 95% cotton body that feels like regular everyday underwear. It is designed for women who want simple, comfortable period protection without the bulk, complexity, or synthetic feel of advanced multi-layer designs.
With both private label and OEM/ODM supported, Model 9039 is the ideal starting product for brands entering the period underwear market for the first time.
The core functional element is the widened and lengthened 3-layer leakproof crotch panel, which is visibly larger than a standard sanitary pad:
Layer 1 — Easy-Wash Soft Cotton (Top): The skin-contact layer uses soft cotton that absorbs menstrual flow quickly and releases easily during washing. Gentle on sensitive skin with anti-bacterial properties.
Layer 2 — Leakproof Membrane (Middle): A health-and-safety-grade waterproof membrane prevents any fluid from penetrating through to the outer fabric, providing reliable leak protection.
Layer 3 — Odor-Control Breathable Layer (Bottom): The outermost layer controls odors while maintaining breathability. A two-way needle construction overcomes the airtight problem common with waterproof membranes, allowing moisture vapor to escape while blocking liquid.
Unlike standard period panties with narrow leakproof strips, Model 9039 features a significantly enlarged leakproof panel:
The leakproof area is wider and longer than a standard sanitary napkin, providing extended coverage from front to back.
Water beads visibly on the leakproof surface, demonstrating the membrane's effectiveness.
The enlarged panel provides confidence during sleep and heavy-flow days, reducing the need for additional sanitary products.
The entire panty body is constructed from 95% Cotton + 5% Spandex — not just the crotch:
Natural Cotton Feel: Unlike synthetic-heavy period panties that feel plasticky or clinical, Model 9039 feels like a regular cotton panty. This is critical for consumer adoption, especially first-time period underwear users.
5% Spandex Stretch: Just enough elastane for comfortable body-conforming stretch without compromising the cotton hand-feel.
Care Label in English: Pre-printed "95% COTTON 5% SPANDEX / MADE IN CHINA" — export-ready.
The rear panel features an enlarged hip-wrap design that extends the leakproof coverage area toward the back:
Prevents rear leakage during sleep or when lying down.
No edge-rolling—the rear panel lies flat against the skin.
Does not tighten the leg—comfortable stretch leg openings with delicate edge finishing.
The waistband is intentionally widened for period-day comfort:
Distributes tension across a wider area, eliminating the digging sensation that standard narrow waistbands cause—especially during bloating.
Outstanding elasticity with no strain, suitable for a wide range of body types.
The mid-rise height provides abdominal warmth and coverage without riding up to high-waist levels.
The leg openings feature comfortable stretch finishing:
Delicate edge construction that lies flat against the inner thigh.
Elastic stretch accommodates different thigh sizes without leaving marks.
No tightening or binding—critical for period comfort when sensitivity is heightened.
Model 9039 is available in 8 color options. The product images show colorways including Black, Red, and Apricot/Skin tone, with the leakproof crotch panel in contrasting grey cotton.

Q1: How does the 3-layer leakproof system compare to using a sanitary pad?
The 3-layer system functions similarly to a built-in pad—absorbing flow on top, blocking leaks in the middle, and controlling odor on the bottom. The key advantage is the widened and lengthened coverage area that is larger than a standard sanitary pad, plus it is reusable and machine-washable.
Q2: Can this replace sanitary pads entirely?
For light to moderate flow days, Model 9039 can be worn alone as a pad replacement. For heavy flow days, it is recommended as a backup layer worn together with a pad, tampon, or menstrual cup for maximum protection.
Q3: Why 95% cotton instead of nylon like other models?
Cotton is the most skin-friendly and breathable natural fiber, making Model 9039 ideal for consumers who prefer natural materials against their skin—especially during the menstrual period when skin sensitivity is heightened. The 95% cotton composition also appeals to the growing "clean/natural" consumer segment.
Q4: Is the leakproof membrane breathable?
Yes. The two-way needle construction in the bottom layer overcomes the airtight problem typical of waterproof membranes, allowing moisture vapor to escape while blocking liquid penetration.
