Medium postal boxes
We have a wide selection of medium-sized mailing boxes at Tiny Box Company that can suit a range of goods, whether you’re shipping A5 documents, books, flowers, or even our medium magnetic gift boxes...
What can I ship in medium postal boxes?
Beauty and wellness products: Skincare sets, hair care products, bath and body items, and beauty gift sets can be neatly packed in medium-sized postal boxes. Their sturdy design ensures that delicate products stay intact.
Books, notebooks and art supplies: Medium postal boxes are great for sending books, sketchpads, or sets of art supplies such as paint tubes, brushes, and pencils. They help keep printed materials flat and protected from bending or damage.
Subscription boxes and gift sets: If you run a subscription box business or sell curated gift sets, medium postal boxes are an excellent choice for neatly presenting multiple products in one package. They help create a premium unboxing experience for customers.
Why choose medium postal boxes?
Strong and durable protection: Made from high-quality cardboard, these boxes offer excellent strength to safeguard items from impact, compression, and handling during transit. Many of our medium postal boxes are also designed to fit within standard courier size and weight limits, helping you save on shipping costs while ensuring maximum efficiency.
Sustainable and eco-friendly: Our medium postal boxes are made from recyclable materials, making them an environmentally conscious packaging choice for businesses and individuals. Opting for sustainable packaging not only reduces waste but also enhances your brand’s green credentials - a win-win!
Easy to assemble and store: With quick-fold designs, our flat-pack boxes are easy to set up, saving you time when packing orders. This also makes them convenient to store in bulk without taking up too much space.
Medium branded postal boxes
Many of our postal boxes can be branded in-house with digital printing at Tiny Box Company, including our A5 corrugated flat mailing boxes and two-piece rigid boxes. Have your logo, message, or full-colour image or design printed directly onto the box, or simply add a branded sticker to a plain box.
Our range also includes several brightly coloured A6 mailing boxes, from apricot crush to sage green, to match your brand colours when sending out products to customers. For more colours and styles of boxes, check out our full gift box range here!
