What transfers to Pakistan (and what doesn't)
💡Transfers ✅
- Multi-pack wardrobe purchase behavior (drives AOV)
- Comfort + leak-proof + overnight core benefits
- PFAS-free / safety as trust proof
- Bamboo/cotton-rich comfort narrative
- Teen / postpartum / overnight sub-segments
⚠️Does NOT transfer ❌
- "Sustainability" as lead message — in PK, savings + hygiene + discretion convert better.

- Open, public marketing tone — PK requires discretion (Risks-and-Sensitivities).
