巴基斯坦采购需求：选举产品，不可擦去的记号笔

I'm reaching out to inquire about your indelible ink marker pens specifically designed for polio vaccination marking. We are looking for high-quality markers that ensure long-lasting visibility and reliability. It's crucial for them to have features like quick-drying ink and resistance to fading, as these markers play a vital role in maintaining accurate vaccination records. Could you please provide detailed specifications, including size options, available colors, and pricing? Additionally, information on bulk purchase discounts, lead times for delivery, and any certifications or compliance with health regulations would be highly appreciated. We aim to place a significant order soon, so your prompt response would be invaluable in our decision-making process. Thank you!
