比利时采购需求：背包、运动包、旅行包、儿童包、促销包、手提包

I'm excited to launch my brand, Waxi, with a unique line of handbags featuring integrated solar panels for charging phones. I'm looking for a manufacturer who can help bring this vision to life. Could you provide details on the minimum order quantity for each design, as well as the customization options available, including materials, colors, and overall design? Additionally, I need information about the specifications for the solar panels and batteries you'll be using in these bags. It would be great to know the estimated price per unit along with lead times for production. Also, are samples available for evaluation? Looking forward to your prompt response!
