I'm interested in ear tags designed for both game animals and cattle. Could you provide detailed information regarding your available options? Specifically, I'd like to know about the materials used, durability, and any color or size variations you offer. Additionally, please share your pricing structure, minimum order quantities, and lead times for delivery. If you have any product catalogs or samples, that would be great to review. Looking forward to your prompt response!
