Built and Led by Ocean Yang, Founder & CEO
After 8 years at Alibaba as a Marketing Manager (2007–2015) working with thousands of cross-border B2B brands, Ocean Yang founded Ljvogues on May 4, 2015 with one goal — build the factory that brands wished they had found earlier. Today he still personally signs off on every material spec and QC protocol in our 8,000m² Shenzhen facility.
Health, Wellness and Insurance
Every team member is covered by full social insurance and an annual factory health check.
97% customer satisfaction rate
Measured across 500+ brand partners over the past 12 months — the number Ocean reviews every Monday.
Family Scholarship Program
Annual scholarships for our employees' children — because the people who build your products deserve more than wages.
What Sets Our Manufacturing Apart
PFAS-Free Lab Verified
Every fabric is third-party tested on finished garments — not just raw rolls — for PFAS, REACH SVHC 253 substances, and OEKO-TEX Standard 100 compliance.
MOQ from 50 Pieces
Validate market fit before committing inventory. Same quality protocol as 50,000-unit production runs.
72-Hour Sampling
In-house pattern, fabric, and prototype team. Most prototypes ship within 3 working days of brief approval.
AQL 2.5 Quality Inspection
Sample-by-sample inspection at 4-needle 6-thread flatlock seams and TPU thermal bonding (18–25 microns) — the same standard our European clients pass through customs.
What We Make
Inside Our 8,000m² Shenzhen Facility
This is what brand founders see when they visit our factory.
4-Layer Leak-Proof Construction
Moisture-wicking top → absorbent core → impermeable TPU membrane → soft outer. Each layer independently tested.
TPU Thermal Bonding 18–25 microns
No glue, no PFAS-treated waterproof coatings. Bonded membrane survives 200+ wash cycles in our in-house wash lab.
4-Needle 6-Thread Flatlock Seams
Chafing-free construction. The same seam architecture used by Lululemon and Athleta on their high-end activewear.
AQL 2.5 Sample Inspection
Every shipment passes our 2.5 Acceptable Quality Limit protocol — tighter than the AQL 4.0 most B2B factories use.
Certifications & Compliance
Additional product-specific test reports (REACH SVHC, CPSIA, Prop 65) available on request.

Eleven years ago, when I started Ljvogues, the OEKO-TEX Class I standard was the goal. Today we have the certificate.

I've spent 11 years running a period underwear factory in Longgang District, Shenzhen, and I can tell you the exact moment most people lose trust in a pair of period underwear.
