Your Top Questions, Clearly Answered
We know packaging can raise many questions, so we’ve made the answers simple and straightforward. From how to place an order and choose the right materials to design options, shipping, and costs, this section clears every doubt so you can move forward with confidence.
- 1What is the minimum order quantity for custom packaging?At CustomBoxesPackaging, we understand that every business has different needs, which is why we offer flexible order quantities. Our minimum order quantity typically starts at 100 boxes, making it easier for startups and small businesses to get premium packaging without committing to huge volumes. For larger companies, we also accommodate bulk orders of thousands of units at highly competitive rates.
- 2Why should I prefer Custom Printed Boxes over the readymade packaging available on other sites?Custom printed boxes give your brand a unique identity that readymade packaging cannot match. With tailored sizes, designs, and finishes, your packaging reflects professionalism and enhances customer experience. Unlike generic boxes, custom solutions strengthen brand recognition, improve product safety, and create a memorable unboxing moment that builds loyalty.
- 3Do you provide free design support?Yes, at CustomBoxesPackaging we provide absolutely free design support with every order. Our expert design team assists you in creating dielines, adjusting layouts, and refining artwork to match your brand identity. Whether you need help with logo placement, color selection, or finishing touches, we ensure your packaging design looks professional, appealing, and ready for production without extra cost.
- 4Why does custom made box packaging cost more than stock boxes on amazon?Custom-made packaging costs more because it is designed specifically for your brand. Unlike stock boxes on Amazon, which are mass-produced in standard sizes, custom boxes are tailored to your product dimensions, printed with your logo, and finished with premium materials or coatings. This customization ensures better product protection, branding impact, and customer experience, which adds value beyond basic packaging.
- 55What is your standard turnaround time for production and delivery?Our standard turnaround time for production and delivery typically ranges between 8 to 12 business days after final design approval. For larger or highly customized orders, timelines may vary slightly depending on materials and finishing options. We also offer expedited services for urgent projects to ensure you never miss a deadline. Once production is complete, shipping is fast, reliable, and free across major regions.
