非洲地区采购需求：永久记号笔、永久墨水、编码打印机、快干墨盒、钢笔墨水、永久性记号笔墨水

I'm looking to procure high-quality indelible ink that contains 20% silver nitrate, specifically designed for election purposes. It's important that the ink meets rigorous standards for durability and visibility, ensuring it remains intact on various surfaces. Could you provide detailed specifications regarding your available products, including pricing, packaging options, and lead times? Additionally, I'd appreciate any insights on compliance with election regulations and testing certifications. Hoping to hear from you soon!
