孟加拉采购需求：水晶玻璃珠、管状玻璃珠、圆形玻璃珠、散装玻璃珠、水滴形玻璃珠、玻璃水晶珠

I'm looking to source rhinestones with different quality options, specifically DMC quality and A quality. It would be great if you could provide detailed specifications for both types, including the sizes available, color options, and any unique features that may set them apart. Additionally, I'm interested in understanding the pricing structure for both qualities and any minimum order quantities that may apply. If you could also share lead times for production and delivery, it would help in planning. Looking forward to your quick response with all the necessary info!
