I'm looking to customize some envelopes along with acrylic clips for a project. Specifically, I need details on the available sizes, colors, and any printing options you offer for the envelopes. Also, please share information on the types of acrylic clips you can provide and if they can be personalized as well. Additionally, it would be great to understand the minimum order quantities, lead times, and pricing structure for these items. I'm interested in options that can enhance branding and add a professional touch. Looking forward to your detailed response!
