With options from cost-effective kraft to premium multicolour with foil accents, you can choose a variant that matches your brand style, budget, and delivery needs.

Custom Mailer Box Sizes

All our mailer boxes can be made in fully custom dimensions for a perfect fit to your products, or ordered in a wide selection of standard sizes ranging from F23 (9.2 × 9.2 × 5 cm) for compact, lightweight items to F112 (42.5 × 52 × 18 cm) for large or bulky goods.

Most variants are available in the full set of 14 sizes, giving you maximum flexibility when matching your box to your product. The Premium Multicolour range is offered in 12 carefully selected sizes to ensure the highest print quality and flawless finish, while still covering the same spectrum from small to extra-large formats.

Custom Mailer Box Material Colour

Custom mailer box variants offer different base materials to suit a variety of branding styles:

One Colour – Kraft (cardboard) or White (bleached cardboard).
White Colour – Kraft (cardboard).
Multicolour – muted – White (bleached cardboard).
Multicolour – saturated – White (bleached cardboard) + Kraft (cardboard) inside the box, resulting in less saturated colours and lower contrast on the inside.
Multicolour – premium – White Outside + White Inside (coated cardboard) or White Outside + Kraft Inside (coated cardboard exterior, cardboard interior).

From natural kraft for a rustic, eco-friendly look to premium coated white surfaces for vibrant, high-definition graphics, you can choose the tone and material that best match your brand identity.

Outside – Available in all variants.
Inside – Available in all variants except Multicolour – saturated.

Custom Mailer Box Adhesive Strip

Seal your custom mailer boxes securely and speed up packing with our adhesive strip options:

One Colour, White Colour, and Multicolour – muted – Choose from no strip for traditional taping, a single peel-and-seal strip for quick dispatch, or a double strip that makes returns as simple as sealing again.
Multicolour – saturated – Offered without an adhesive strip.
Multicolour – premium – Designed for high-end presentation, offered without adhesive strips to maintain a sleek, uninterrupted surface.

Whether you need fast fulfillment with minimal packing materials or the lowest possible cost per unit, you can select the strip configuration that best suits your workflow and budget.

Custom Mailer Box Foil (Multicolour – premium only)

Elevate your custom mailer box with foil stamping in our Premium Multicolour range. Choose Glossy Foil for a striking shine that catches the light or Matte Foil for a smooth, refined elegance.

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.
