I'm currently working on a new subscription project called Bilbox and need a dependable supplier for custom shipping boxes. I'm looking for strong corrugated cardboard boxes that are suitable for shipping. The dimensions should be around 30 × 20 × 15 cm, and I'd like options for customizable printing to include my logo and chosen colors. Finishing can be either matte or standard. Initially, I'm looking for around 50 units, but I can go up to 100 if your MOQ permits. Could you please provide me with a quote for both quantities? I also need information on sample costs, production lead time, and available material options like E-flute and thickness. Additionally, I'd appreciate details on shipping methods and costs to France, including express, air, and sea options. Ensuring high-quality products and reliability is crucial, as I'm aiming for a long-term partnership with the right supplier.
