B Corp certified — Personal care products
WUKA specializes in period underwear—a functional category where longevity claims are harder to substantiate than traditional apparel. We could not find detailed evidence of material sourcing (fiber origin, yarn specifications), stitching density, or reinforcement protocols. The brand mentions OEKO-TEX certification and some eco-conscious production steps, but full supply chain transparency and independent third-party certifications beyond fabric standards remain areas for growth. A published care guide, warranty terms, or take-back program would meaningfully strengthen the longevity score.
Every brand on Oras is independently researched across five pillars: material quality, construction and craftsmanship, longevity and repairability, sustainability and ethics, and design philosophy. We use a consistent framework so you can compare brands meaningfully.
Oras does not sell products directly. We connect you to the brand's own site. We may earn a small affiliate commission, but this never influences our research or which brands we feature.
