Questions about this box

What fits in a 310 x 230 x 105mm box?

A4 documents, folders and books lie flat (A4 is 297 x 210mm), with 105mm of height for shoes, clothing, gift sets and bundles of products.

Is the size inside or outside the box?

All sizes are internal (length x width x height), measured inside the box. The outside is a few millimetres bigger because of the board thickness.

Can I get this size in other colours or styles?

Yes. This A4 size comes in white, brown, black, pinks, blues, green, red, purple, lavender and orange, in diecut, tuck-front and self-seal styles. Use the "Same size, more colours & styles" link above the description to see them all.

What does "Full" or "Premium" colour mean?

"Full" colour boxes (for example Full Black or Full Rose Pink) are printed the same colour inside and out, so the box looks finished the moment it's opened. Most other coloured boxes are coloured outside with a natural kraft inside.

Are the boxes delivered flat?

Yes. The boxes are delivered flat in packs and fold into shape in seconds, so they take up very little shelf space.

Can I print my logo on the box?

Yes. We make custom printed boxes from 1,000 units, usually in around 2 weeks. Get a quote. For smaller runs, a printed sticker or stamp on a plain box works well.

What does the pack size mean?

The pack size is how many boxes come in one pack, for example x100 is a pack of 100 boxes. "Number of packs" sets how many packs you get, so x100 with 2 packs is 200 boxes.

Can I return the boxes, or pick up my order?

Yes to both. We offer 90-day returns on unopened items (see our refund policy), and you can choose pickup at checkout and collect from Minto NSW or Braeside VIC, Monday to Friday 9am to 4pm.
