巴西采购需求：批发、伸缩、手提箱、手柄、散装、供应商

I'm currently sourcing trolley case handles and would like to request a detailed quote. Please provide information on your available options, including material types, color variations, and any customization possibilities. Additionally, it would be great to know the pricing tiers based on order quantities, lead times for production, and shipping options. If there are any minimum order requirements or bulk discounts, please include those details as well. Thank you!
