Protect your apparel with sturdy material options

Your custom t-shirt mailer box is built from robust corrugated cardboard, ensuring your apparel arrives in excellent condition. Choose between standard corrugated cardboard, corrugated bleached cardboard for a brighter base, or corrugated cardboard coated for a refined finish. With grammage options ranging from 358 gsm to 510 gsm, you can select the right level of durability for your specific product and shipping needs. The material provides a strong structure to safeguard items during transit, preventing damage from impacts or crushing.

Create a distinct brand look

Customise your t-shirt mailer box with a range of material colours to reflect your brand's aesthetic. Options include classic kraft, clean white, or a white-brown combination for a natural yet polished appearance. You can also specify kraft inside or white inside, allowing you to control the interior presentation of your packaging. This choice helps establish a consistent visual identity from the moment your customer opens their package.

Fit your garments perfectly

Available in large, small, and medium sizes, these custom mailer boxes are designed to accommodate various t-shirt dimensions. The range of sizes ensures a snug fit for your apparel, reducing movement during transit and helping to prevent creasing. Each size is engineered to fit standard courier and parcel-locker dimensions, including services like InPost, DPD, Royal Mail, and DHL, streamlining your shipping process and helping to avoid extra postage costs from oversized packaging.

Make your design pop with varied print options

Bring your brand's visuals to life with extensive printing capabilities. Choose from one colour for a minimalist design, multicolour – muted for subtle branding, multicolour – saturated for vivid graphics, or multicolour – premium for high-fidelity images. You can apply your custom print to the outside of the box, the inside, or both, creating an immersive unboxing experience that reinforces your brand identity from every angle.

Enhance presentation with finishing touches

Add a professional finish to your custom t-shirt mailer box with optional foils. A glossy foil provides a reflective, polished surface, while a matte foil offers a sophisticated, non-reflective look. For added security and convenience, select a single or double adhesive strip option to ensure your packages are securely sealed for transit and easy for customers to open.
