I'm interested in exploring options for a specific set of liquid ink pens with a fine 0.5 mm tip. It would be great to know the variety of colors and designs available in your collection, as well as any unique features that could differentiate your pens from others on the market. Additionally, I'd appreciate details on pricing, minimum order quantities, packaging options, and lead times for delivery. If you have any catalogs or samples that can showcase your products, please let me know. Looking forward to your response!
