I'm looking to order custom lapel pins featuring my university's logo. These will be used for various events and occasions to promote school spirit and unity among students and alumni. Could you please provide details on the available materials, pricing, minimum order quantities, and estimated production time? I'm especially interested in options that will allow for some customization in terms of design and finishing. Thanks!
