What Are Postal Boxes?
Postal boxes UK are die-cut corrugated boxes designed specifically for posting and shipping through Royal Mail and other UK courier services. Also called shipping boxes or mailing boxes, they feature self-locking tabs that fold together without tape, making packing fast and efficient.
Available in brown kraft or white card stock, postal boxes are the most popular packaging choice for UK e-commerce businesses, eBay sellers, Amazon FBA and online retailers. They protect products during transit while being lightweight to minimise shipping costs.
At Wabs Print, we supply postal boxes in Royal Mail compliant sizes plus custom dimensions. Available plain or custom printed with your branding. No minimum order. Free UK delivery to England, Scotland, Wales and Northern Ireland.

Postal Boxes vs Mailer Boxes: What's the Difference?
Both are die-cut self-locking boxes, but they serve slightly different purposes:
Bottom line: Both use self-locking tabs and require no tape. Choose postal boxes for cost-effective shipping. Choose mailer boxes when premium presentation matters. Many businesses use both.
Don't believe packaging suppliers who say standard boxes work internationally. We over-engineer for Blowerband.com's USA shipments — double-wall, reinforced corners, costs £0.85 more. Damage rate under 1% in 5 years. Standard packaging won't survive crossing an ocean. We've seen it fail too many times.
Honest truth? Most packaging suppliers sell you the same boxes for UK and international shipping. That's a mistake. Transatlantic shipping is brutal — thrown around, crushed, temperature swings, humidity in containers. If you're shipping outside UK, expect to pay 40-60% more for proper protection. Anything less is gambling with your product.

Why UK Businesses Choose Wabs Print
After 15 years, we've learned what actually matters. Here's what our clients say:
When Things Go Wrong (Janeys Cafe, London)
Janeys Cafe been ordering greaseproof sheets from us for years. Late 2025, production error: 200 sheets in their order came out with misaligned printing. They called, understandably frustrated — needed them for weekend rush.
We didn't argue about whose fault it was. Sent 300 replacement sheets same day, covered the courier cost ourselves. After 15 years in this business, we've learned errors happen. It's how you fix them that matters. Janeys still orders from us every month. Trust isn't built when everything's perfect. It's built when something goes wrong and you make it right.
The "Expensive" Option That Paid For Itself (Blanka Soap UK)
Blanka Soap UK — premium handmade soaps, selling £8-12 per bar. They were using basic paper labels. Cost: £0.08 per label. Looked... homemade (not in good way).
We recommended switching to gold foil stickers. Cost: £0.45 per label. They hesitated. That's £0.37 more per bar.
Here's what happened: Their Instagram engagement jumped. Customers started posting close-up photos of the gold foil catching light. The premium positioning matched the premium price point. They told us sales increased enough that the £0.37 extra per label paid for itself in the first month. Premium products need premium packaging. Sometimes the "expensive" option is actually the most profitable one.
Don't Use Standard Boxes for International Shipping (Blowerband.com)
Blowerband.com ships custom boxes from UK to USA. Been working with them 5+ years.
The challenge? Transatlantic shipping is brutal. Boxes get thrown around, crushed under pallets, exposed to temperature swings, humidity in shipping containers.
We over-engineer their boxes specifically for international shipping. Double-wall construction. Reinforced corners. Costs £0.85 more per box than standard. Result? In 5 years of regular USA shipments, damage rate under 1%. Their customers receive pristine boxes after crossing an ocean. Worth every penny of that £0.85. If you're shipping internationally, don't use standard packaging. It won't survive the journey.
The Best Relationships Are Partnerships (Littlepickle Memories)
Littlepickle Memories — one of our favorite long-term clients.
What makes them great? They actually listen. When we recommend something (like upgrading board thickness for their product weight), they trust our experience instead of just going for cheapest option.
Result? Zero issues. Consistent quality. No emergency "our boxes are falling apart" calls. Their customers get perfect packaging every time. After 15 years in this business, we can spot which businesses will succeed. It's the ones who value quality over saving 20p per box. The best client relationships aren't the biggest orders. They're the ones where we work together, not just fulfill orders.
