I'm reaching out to inquire about a specific type of graph paper that I'm interested in sourcing. I'm looking for high-quality paper with precise measurements: it should be 1243mm wide and 150mm long. The intended use for this paper is for technical drawings and detailed designs, so accuracy and durability are key. Could you provide details on the specifications, including the paper weight, grid spacing, and available quantities? Additionally, I'd appreciate information about pricing, lead times, and any potential discounts for bulk orders. If you have samples available, that would be great to review as well. Looking forward to your prompt reply!
