土耳其采购需求：涤纶亮片纱

I'm interested in sourcing sequin yarn for an upcoming project. Could you provide detailed information about your product options in this category? Specifically, I'm looking for various colors, textures, and sizes available. It would also be great to know about the types of sequins you offer, such as flat, cupped, or any other unique variations. Additionally, I'd appreciate any information on minimum order quantities, pricing tiers, and lead times for delivery. If you have a catalog or samples available, please let me know how I can obtain those. I'm keen on establishing a reliable supplier relationship and look forward to exploring your offerings in sequin yarn.
