荷兰采购需求：宠物五金配件、金属环、金属标志、宠物吊牌、金属钩、金属链

I'm seeking a manufacturer for a custom crescent-shaped metal clutch frame, which is a key piece for my brand. The design needs to be smoothly curved, with a kiss-lock clasp featuring two round metal balls. I prefer materials like zinc alloy or brass, and I'm open to your suggestions. For this order, I need 25 pieces in polished gold and 25 in polished silver, totaling 50. The frames should have small reinforced holes on both sides for handle attachment and allow for bead embroidery. It's crucial that interior edges are smooth to protect the fabric. Could you confirm your capability to produce this? What's your minimum order quantity? I'd like to know the sample cost and production lead time, along with the unit pricing for my total order. Also, please let me know if you require any sketches or additional info from my side to move forward. I can provide reference drawings immediately upon your reply.
