I'm looking to order personalized key chains for my company, PB12 CLEANING SERVICES. I'm interested in placing an order for 200 units. Could you provide me with the pricing details for this quantity? Also, I'd like to know about any customization options you offer, including design choices and material types. Additionally, please share information regarding the lead time for production and delivery. It would be great if you could send over any samples or catalogs of your previous work. I'm eager to make a decision quickly, so any details you can provide would be really helpful. Thanks!
