I'm interested in sourcing custom bags specifically designed for coffee. I'm looking for a sleek and modern aesthetic that features a matte black finish, complemented by vibrant red accents. It's essential that the bags not only look great but also provide practical functionality for coffee enthusiasts. Additionally, I would prefer to explore options for different sizes and potential design variations that can highlight our brand.

Looking forward to your response and any samples you might have!
