I'm reaching out to explore your range of fasteners, as I've heard positive feedback about your products. Specifically, I'm interested in understanding the different types you offer, along with their specifications, materials, and any relevant certifications you may have. This info will help me assess which products align best with our sourcing needs. Additionally, I'd appreciate it if you could provide details on pricing, minimum order quantities, and lead times for delivery. If you have a catalog or a product brochure, that would be super helpful as well. Looking forward to your prompt response so we can discuss potential collaboration opportunities!
