I'm interested in sourcing medical earrings and would like more details about your offerings. Specifically, I'm looking for options that comply with industry standards for safety and biocompatibility.

Additionally, I'd appreciate your pricing structure, minimum order quantities, and lead times for production and delivery. If you have a catalog or samples, that would be great to review. Looking forward to your prompt response!
