尼日利亚采购需求：软眼镜盒，硬眼镜盒，太阳镜盒托，铁质眼镜盒，手工眼镜盒，多功能收纳盒

We're in the process of launching a premium eyewear line and need a luxury sunglasses case featuring a custom locking mechanism. We envision two vertical retractable metal loops that are flush with the case surface when not in use. When locking, these loops should lift and meet in the center, designed to fit a padlock that we'll either supply or customize. Could you let us know if you have experience with this type of retractable mechanism? Also, do you offer customizable padlocks? Please share available options. We'd appreciate info on your minimum order quantities and estimated pricing for the cases, as well as the branding techniques you provide, like embossed logos or metal plates. If you need any reference sketches, just ask!
