美国采购需求：应用、咖啡馆、冷杯、双层壁、双层壁杯、纸杯

I'm looking to explore the potential of butterfly cups in the Saudi market and would love to receive some samples for evaluation. Specifically, I'm interested in double wall options for hot beverages and larger sizes for cold drinks. Could you send me samples in a couple of sizes for both categories? This will help me assess their appeal and quality before moving forward with potential orders. Thanks for your assistance!
