I'm interested in understanding your sourcing strategy a bit better. Could you let me know which country or countries you're currently sourcing your materials or products from? It would be helpful to gain insight into your supply chain decisions, as this information can influence our partnership approach. Additionally, if there are specific reasons for choosing those sourcing locations—like cost efficiency, quality, or sustainability—I'd love to hear about them. This context will help us align our expectations and ensure we're on the same page moving forward. Looking forward to your response!
