Protect your products with robust materials

Your custom mailer box is constructed from corrugated cardboard, available in kraft, white, or a white-brown combination. For enhanced durability, options include corrugated bleached cardboard and corrugated cardboard coated. This range of materials, with grammages from 358 gsm to 510 gsm, provides a sturdy enclosure for your items during transit, ensuring they arrive securely.

Create a memorable unboxing experience

Customise the interior of your mailer box to extend your brand's presence. With print coverage options for the inside, outside, or both, you can apply your design across all visible surfaces. Choose between multicolour muted, saturated, or premium printing to match your brand's aesthetic, making every unboxing a distinctive moment for your customers.

Sizes to fit your specific needs

Available in small, medium, and large, these mailer boxes are designed to accommodate a variety of products. Each box maintains a dimensional tolerance of ±2-4mm, ensuring a consistent fit for your items. Furthermore, all sizes are engineered to fit standard courier and parcel-locker dimensions, simplifying your shipping logistics.

Enhance your design with professional finishes

Apply a glossy or matte foil finish to your mailer box to give it a distinct look. These finishes add a layer of visual texture and can highlight specific elements of your design, creating a polished presentation.

For added security and convenience, custom mailer boxes can be equipped with a single or double adhesive strip. This feature provides a strong seal for transit and offers an easy-open solution for recipients.

KraftKraft Paper is a brown-colored material which gives a organic, rustic appearance. This type of material is commonly used for packaging products that benefit from a natural or "green" presentation.
WhiteThis product is available in white.
White - BrownThis product comes in white and brown.
Kraft insideRecommended for bold, eye-catching prints on the outside, combined with a natural kraft finish on the inside for a more organic look and feel.
White insideThe best choice for vivid printing on all sides of the packaging. Features double-sided coated cardboard, creating a smooth, premium surface for vibrant, high-quality prints inside and out.

One ColourPrinting with a single CMYK color keeps costs low and is perfect for minimalist designs or when multi-color detail isn’t needed.
White ColourEach print is made with white ink using UV printing technology. It’s ideal for creating strong contrasts on kraft cardboard and achieving a premium look. This option is more costly than standard CMYK printing due to the use of a different, more advanced technology.
Multicolour – mutedThe most affordable option for multi-colour printing. It gives your design soft, slightly faded tones, perfect for natural and rustic styles. This option doesn’t support background printing. For full background coverage, choose Multicolour – saturated or Multicolour – premium.
Multicolour – saturatedAffordable multicolour printing on bleached cardboard. The bright white, uncoated surface provides good colour accuracy with a softer, more natural finish. As the inside of the box is printed on the brown side of the cardboard, colours on the inside may appear less saturated. Perfect for designs where true-to-design colours matter but an ultra-glossy finish is not required.
Multicolour – premiumOur top-tier multicolour printing on coated cardboard for maximum vibrancy and detail. The ultra-smooth coating keeps ink on the surface, producing sharp, high-definition results - even for photographic imagery and complex graphics. Ideal when you want your packaging to stand out with premium, eye-catching colours.

Optional adhesive strips provide secure closure for both shipping and returns. To make unboxing experience more unique, you can add a polymailer as an additional cover and surprise your customers.

Can I order a Custom Mailer Box in custom sizes?

Yes, we offer the most popular standard sizes on the market, but you can design any custom size directly in our online editor or using a dieline. To order a custom size, open the editor and check the top field in the size picker. Please note that custom sizes may have bigger minimum order quantities.

Are Custom Mailer Boxes environmentally friendly?

Custom Mailer Boxes without any add-ons are environmentally friendly. They are partially made of recycled cardboard, making our products biodegradable and recyclable. If you choose additional finishes such as UV or foil, these properties may change depending on the selected finish.

What are the standard sizes recommended for clothing?

Our Custom Mailer Boxes can be personalised to complement fashion brands, creating packaging that reflects your style and enhances the customer experience. Choose the F79 size (36.4 × 31.4 × 12.5 cm) for larger garments like blouses, trousers, or jackets, or the F71 size (35 × 26 × 10 cm) for smaller pieces. Always make sure to measure your products first, and remember that you can order our sample pack to double-check the dimensions.

What are the standard sizes recommended for shoes?

The F79 box (36.4 × 31.4 × 12.5 cm) is tailored for the fashion industry and works well for shipping standard shoes. However, we always recommend measuring the product first, especially for boots or larger men’s footwear, to ensure it fits the selected box size. To make sure you've got the dimensions right, order our sample pack.

Is there any difference in printing techniques for different order quantities?

Yes, the printing technique is adjusted to the ordered quantity and designs to make the production process efficient. For example, for smaller quantities of white print on kraft material, we use UV printing, while larger quantities are printed with flexographic printing. The main differences relate to colour saturation. UV printing has a high saturation point, which generally produces rich whites with high contrast. Flexographic printing has a lower saturation point and produces softer white prints, especially against the natural brown cardboard.
