I'm looking to source high-quality seed beads for an upcoming project. Specifically, I'm interested in understanding the variety you offer, including different sizes, colors, and finishes. If you could also provide some information on your minimum order quantities and pricing, that would be really helpful. Additionally, I'd like to know about the lead times for orders and whether you can accommodate custom color requests. Please share any catalogs or samples you might have available, as this would assist me in making a well-informed decision. Looking forward to your detailed response!
