I'm reaching out to inquire about washers. Specifically, I'm interested in details regarding the types you offer, including materials, sizes, and any special features you might have. It would be great to know what your minimum order quantities are and if there are any bulk purchase discounts available. Additionally, please send over your pricing information and lead times for production and delivery. If you have a catalog or product specifications, I'd love to review those as well. Looking forward to your prompt response so we can explore potential collaboration!
