Questions about this box
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.
What does the pack size mean?
The pack size is how many boxes come in one pack, for example x25 is a pack of 25 boxes. "Number of packs" sets how many packs you get, so x25 with 2 packs is 50 boxes.
Are the boxes delivered flat?
Yes. Regular cartons are delivered flat to save space and fold into shape in seconds.
How do I seal the box?
Use 48mm packaging tape along the top and bottom seams. For heavy items, also tape across both ends. See "How to fold & seal" above.
Can I return the boxes?
Yes. We offer 90-day returns on unopened items. See our refund policy.
Can I pick up my order?
Yes. Choose pickup at checkout and collect from Minto NSW or Braeside VIC, Monday to Friday 9am to 4pm.
Can you make a custom size?
Yes. Custom cartons start from 1,000 units and take around 2 weeks. Get a quote.
Do you offer bulk pricing?
Yes. Bigger packs cost less per box, and pallet quantities cost less again. See our bulk deals.
Customer Reviews
Overall rating: 4.9 / 5 from 9 reviews.
A great way to line a package to add that special touch
This is a fantastic box for 5kg Extra Large Flat Rate satchels from Australia Post. There are two different types of this size box - "PLUS" and regular. The plus is a lot thicker and sturdier - great for items which need added protection. The inside of the box is very roomy and allows you to package a vast range of products while leaving room for added packaging / protection during transit. HIGHLY recommend this box from EBPak. In the past, I have bought this box from other sellers / companies but they have been very thin and not as great quality.
Excellent boxes, great service, thank you
Book wraps are great. Padded mailers OK but rather thin. Mailing boxes a little light but OK
These boxes are really EXCELLENT! I've been buying them for years. These are the "PLUS" version - so the corrugated cardboard is thick and provides a decent layer of protection. They fit snuggly in a 5kg Australia Post satchel and are one of my favourite packaging boxes available. HIGHLY RECOMMEND!
Good quality
Great products and wonderful service, thank you
