Common questions
How do custom postal boxes protect fragile items during rough courier transit?
Fluted corrugated walls absorb shocks, vibration, and stacking pressure during transit. Choosing a rigid E-flute or B-flute structure prevents corner crushing and punctures, keeping delicate items like glass bottles or electronics completely safe inside.
Can these boxes fit standard Royal Mail letter box dimensions to reduce shipping costs?
Yes. You can order exact Royal Mail Large Letter or Small Parcel dimensions. This ensures your packages drop directly through standard domestic letterboxes, reducing missed deliveries and lowering overall postage rates.
Are these mailing boxes suitable for shipping wax melts, candles, or oil-based cosmetics?
Yes. You can add internal grease-resistant barrier coatings or protective laminations. These barriers stop essential oils, fragrance oils, and melted waxes from leaching into the paperboard fibers during hot weather shipping.
Can I include dual adhesive peel-and-seal strips for customer returns?
Yes. Adding a double peel-and-seal strip with a tear-strip opener makes unboxing effortless for your customer while enabling easy, tamper-evident resealing if they need to return an item in the same box.
How do I prevent dark-printed mailing boxes from scuffing during transit?
Applying an anti-scratch matte or gloss lamination protects full-coverage exterior printing from scuffs, friction marks, and moisture during automated postal sorting and shipping.

The printed colour matched our brand proof almost perfectly — no washed-out blues like the last supplier gave us. Crash-lock base holds our jars snug with zero rattling in transit.
RARebecca A.2/14/20265.0
Third reorder now. Consistent board quality every single time and the crease lines fold clean without cracking the print.
HLHannah L.3/26/20265.0
Honestly obsessed with how the full-bleed floral print turned out. The matte board feels premium and our unboxing videos have never looked this good.
JPJames P.2/6/20265.0
Needed a small first run to test the market and the low MOQ made it possible. Quality was identical when we scaled to 2,000.
DRDiego R.3/19/20265.0
Ordered a run of activity-kit boxes with a die-cut handle and window — the finish is spotless and the kids love them. Studio sorted the dieline for us in a day.
AKAisha K.1/30/20265.0
Customer service actually replies within a few hours like they promise. They caught a bleed issue in my artwork before it went to print.
AOAmara O.3/11/20265.0
Rigid gift boxes with a soft-touch lid and printed inner — exactly the luxury feel we wanted for our candle sets. Reorder was even easier than the first time.
MVMarco V.1/22/20265.0
Sturdy corrugated that survived a rough courier journey with no dents. The FSC board was a big selling point for our eco-conscious customers.
SCSofia C.2/28/20265.0
The window box with the printed stamp detailing is stunning in person. Turnaround beat the quoted lead time and the samples arrived free before we committed.

The free dieline template made designing so much less stressful. Everything lined up perfectly on the printed box.
