印度采购需求：注塑模具，塑料注塑件，定制塑料件，汽车模具，医疗零件模具，家用模具

I'm looking to purchase between 20,000 and 30,000 LED wristbands for an upcoming event. It's crucial that these wristbands are durable, bright, and have different lighting modes. Please provide details on pricing, minimum order quantities, and lead times for production and delivery. Additionally, I'd like to know about customization options, such as colors and logo printing, if available. Looking forward to your prompt response!
