Inquiry about Water Writing Fabric for Chinese Calligraphy NEW

I am looking for blank water writing fabric for Chinese calligraphy practice. The fabric must be completely plain—no grids, characters, or printed patterns. When wet with clean water, it should turn dark, and then dry back to its original color. I need the fabric cut to specific sizes: the preferred usable writing area is 200 cm in length and 39.5 cm in width. If 200 cm is not available, a minimum usable length of 140 cm is acceptable. I require 10 pieces for this initial inquiry. Please provide the following details: - Exact available usable writing dimensions, total fabric piece dimensions, and full dimensions including any border or scroll if applicable - A full-width photo and a video demonstrating writing and drying on the actual fabric - Material composition and any existing test reports - Unit price, total price, currency, and quotation validity - Cutting and packaging costs, total packaging weight and carton dimensions, and domestic delivery cost - If you can ship to Spain postal code 39700, please separate the international freight, taxes, and customs clearance costs; if export is not possible, I can evaluate domestic delivery terms - Whether you manufacture the fabric yourselves or source from others This is a quotation request only. Please do not cut, produce, charge, or arrange shipment without my explicit written confirmation. I look forward to your detailed information.}
