Size Options and Ideal Applications
We offer five versatile sizes, each tailored to specific product dimensions and shipping needs. Below is a detailed breakdown of each size, its advantages, and the best use cases for your business.
- 120x110x35mm / 4.7×4.3×1.4 inch: This slender profile is ideal for flat or small items such as smartphone cases, jewelry boxes, small cosmetics, or greeting cards. Its shallow depth prevents product shifting, ensuring a snug fit for lightweight goods. Perfect for retail stores that gift-wrap accessories or e-commerce sellers shipping single items.
- 120x120x40mm / 4.7×4.7×1.6 inch: A square design that excels for compact electronics like Bluetooth earbuds, small power banks, or sample-sized skincare sets. The uniform shape allows efficient stacking in warehouse storage, and the thickness can be customized to protect delicate components against impact.
- 130x120x50mm / 5.1×4.7×2.0 inch: A mid-depth box suitable for standard packaging items such as compact cameras, small photo frames, or portable speakers. Its increased height accommodates products with slight depth, offering ample cushioning without excessive bulk for cost-effective shipping.
- 130x80x25mm / 5.1×3.1×1.0 inch: This slim, long format is perfect for stationery like pens, rulers, or small tools, as well as lightweight apparel such as folded scarves or ties. The narrow width minimizes material waste while providing a professional presentation for gift shops.
- 130x80x40mm / 5.1×3.1×1.6 inch: A robust option for thicker items like pocket notebooks, small desk organizers, or premium soap bars. The extra depth allows for layered padding, making it a top choice for artisan brands that prioritize a luxury tactile feel.

Frequently Asked Questions
1. Are these boxes truly tape-free, and how secure is the self-locking mechanism?
Yes, the Orange Self-Locking Cardboard Mailer Boxes are engineered to be completely tape-free. They use interlocking tabs that are precision-cut to snap together and hold firm. This mechanism is designed to withstand the rigors of shipping, including handling by carriers and stacking during transit. For most standard-weight products, the lock remains secure without additional reinforcement. However, for extremely heavy or fragile items, we recommend selecting a thicker corrugated layer or adding optional corner protectors. The one-piece construction minimizes weak points, ensuring the box stays intact from your facility to the customer’s doorstep.
2. Can I customize the corrugated thickness, and what are the available options?
Absolutely. You can choose from a range of multi-layer corrugated thicknesses, typically single-wall (1.5mm-3mm), double-wall (3mm-5mm), or triple-wall (5mm-7mm) depending on your product’s protection needs. For lightweight items like jewelry, a thinner single-wall option is cost-effective. For heavier goods like tools or electronics, a double-wall or triple-wall option is ideal. Paperboxify can also provide custom thicknesses upon request. This flexibility ensures you pay only for the level of protection required, optimizing your budget and reducing waste. We also offer samples so you can test the rigidity before placing a bulk order.
3. How do I get started with ordering and what are the lead times for custom printing?
To start, simply contact us with your desired size (e.g., 120x110x35mm or 130x80x40mm), corrugated thickness, and design requirements. We typically require 7-10 business days for sample creation and approval, followed by 15-20 business days for mass production depending on order volume. We also offer expedited services for urgent needs. For Amazon FBA sellers, we can ensure that your packaging adheres to Amazon’s dimensional and labeling guidelines, including fitting within FBA’s box size limits. Our team will coordinate with you to confirm that the custom logo and any barcodes are integrated properly, making the entire process seamless from design to delivery.
