A collection of our postal boxes suitable for A3 size items
Designed specifically for A3 sized items, A3 postal boxes offer an exceptional solution for shipping and storing materials such as papers, documents, brochures, and even smaller items like photographs. Each box ensures contents are well-protected during transit, mitigating the risk of damage and ensuring quality delivery.
The high-quality construction of these boxes reflects a commitment to reliable packaging. Made from rigid, flute corrugated board, these A3 postal boxes are more lightweight than double walled A3 boxes yet provide optimal protection through their triple thickness on the sides. Ship your items with confidence - the sturdy support ensures your packages stay safe without adding extra weight. These boxes are available in white and classic Kraft brown finishes, catering to different aesthetic preferences - whether for gifting or postal needs.
A3 postal boxes are fully recyclable, aligning with the priorities of eco-conscious businesses and their packaging needs. To ensure you can find the right size, RAJA also offers A4 postal boxes and A5 postal boxes in popular sizes and styles to suit you.
