Our mailing boxes and cartons cover everything from small postal boxes for accessories to larger cartons for bulkier items, all held in UK stock at Parcelsend for same-day despatch. If you need a tape-free option, see our self-seal postal boxes.

How to choose the right mailing box or carton

Start with the size and weight of what you're sending, then check it against the Royal Mail Parcel Post System bands before you order.

Matching box size to your product

Small items such as jewellery, cosmetics or accessories usually sit within the Large Letter or Small Parcel bands, while larger cartons suit bulkier stock, multi-item orders or retail despatch.

Brown or white cardboard?

Both are equally sturdy; the choice comes down to presentation. Brown kraft gives a neutral, practical finish, while white offers a cleaner retail look - browse brown cardboard postal boxes and white cardboard postal boxes to compare.

Why order mailing boxes & cartons from Parcelsend UK

Frequently Asked Questions

What sizes of mailing boxes and cartons do you stock?

We stock a wide range, from small postal boxes suited to accessories and cosmetics up to larger cartons for bulkier products, so you can match the box to your item rather than over-ordering one size.

Are these boxes suitable for Royal Mail postage?

Yes, many sizes fall within the Royal Mail Parcel Post System bands - Large Letter (up to 353×250×25mm, 750g), Small Parcel (up to 450×350×160mm) or Medium Parcel (up to 610×460×460mm) - so check your item against these before choosing.

Is the cardboard recyclable?

Yes, our mailing boxes and cartons are made from recyclable cardboard, so customers can flatten and recycle the packaging through standard kerbside collection.

What's the difference between brown and white boxes in this range?

They're the same sturdy construction - the difference is purely finish. Brown kraft gives a neutral, practical look while white offers a cleaner presentation; see our white cardboard postal boxes for the premium option.

How quickly will my order be despatched?

All boxes in this range are held in UK stock, so orders placed before our daily cut-off are despatched the same day.

Can I get these boxes printed with my logo?

This range is supplied plain; for custom-printed versions with your artwork, see our personalised boxes collection.
