Pack of 20 ColomPac CP065.52.020 shipping boxes with inner dimensions 22.5 x 14.5 x 3.4 cm, designed for mailing flat or low-profile items. These ready-to-use cardboard mailers offer a compact, uniform packaging option for deliveries, returns and storage. The internal size fits documents, brochures, small electronics, printed materials and other slim items that require protection but minimal bulk during transit.

Advantages

These shipping boxes combine consistent internal dimensions with a lightweight construction to reduce volumetric weight in postal calculations. Their flat profile minimizes wasted space and helps maintain a neat presentation for e-commerce orders. The pack format provides a predictable supply for regular shipping operations and reduces the need for ad-hoc cutting or folding. Materials are selected to protect contents from bending and light impacts while remaining easy to handle and store.

How to use

Place the item centrally inside the box using additional protective material (e.g., bubble wrap or paper) if required for fragile contents. Close and secure the mailer according to its closure design; add tamper-evident tape or labels where needed. Affix address and postage information on the external surface, ensuring labels do not cover seams or closure mechanisms. For return shipments, include a packing slip or return label inside the box if required by your process.

Usage recommendations

For optimum protection of fragile or valuable items, add internal cushioning and consider double-boxing for high-risk shipments. Verify parcel dimensions against carrier requirements to optimise postage costs. Store the boxes flat in a dry environment to preserve shape and ease of use.
