Unlimited Customization

Your mailer box is a blank canvas. Here is everything you can tailor to your brand and product:

Size & Structure

We produce mailer boxes custom in any dimension. The industry-standard size is 9.5″ x 7.75″ x 4″ (interior), but we custom-cut every order to your exact product measurements to minimize void fill and reduce shipping weight.

Material Options:

• E-flute corrugated — light, clean print surface, great for standard ecommerce
• B-flute corrugated — a step up in strength for heavier or fragile items
• Kraft corrugated — that natural brown, handmade look brands lean into for an eco-first identity
• White corrugated — bright base that makes colors and photography pop
• Rigid paperboard — the premium option, built for cosmetics, gifting, and luxury unboxing

Printing

We offer the full range of print methods to match your quality and budget requirements:

• CMYK full-color digital printing ideal for photographic or gradient-heavy artwork
• Offset lithographic printing offers the highest color fidelity for large runs
• Flexographic printing is cost-effective for single or two-color brand marks
• Screen printing for bold, solid colors with excellent coverage
• Pantone-matched printing offers exact brand color replication
• All inks are available in water-based or soy-based formulations for eco-compliant packaging.

Finishes

Upgrade your surface with:

• Matte or gloss lamination: protection and premium feel
• Soft-touch matte coating: velvety texture that stands out on shelf and in hand
• Aqueous coating: fast-dry, scuff-resistant clear coat
• Spot or flood UV gloss: high-shine highlights on logos or key visuals
• Gold or silver foil stamping: metallic accents for luxury packaging
• Embossing or debossing: raised or recessed brand marks and logos

Add-Ons

Enhance the unboxing moment with our customized mailing boxes that offer:

• Tissue paper, ribbon pulls, and bow tie closures
• Magnetic closure upgrades
• Tear strips for easy opening
• QR code panels and NFC integration
• Personalized inserts and thank-you cards

Explore Our Full Mailer Box Collection

Every mailer box we make starts from the same core construction and process described above — the difference is in sizing, finish, and the industry it’s built for. Use this page as your guide, then head to the style that matches what you’re shipping:

• Small Mailer Boxes — right-sized for jewelry, accessories, and other compact products where a standard mailer box wastes space and money
• Black Mailer Boxes — matte or gloss black finishes for brands that want a bold, minimal look
• Colored Mailer Boxes — full-color exteriors for brands built around a specific palette
• Apparel Mailer Boxes — built around folded garments, with sizing that keeps clothing wrinkle-free in transit
• Candle Mailer Boxes — reinforced construction and snug inserts for fragile, top-heavy products

Built to Survive Real Shipping Conditions

Our branded mailer boxes are manufactured from high-grade corrugated cardboard with a standard three-layer fluted construction. The inner flute acts as a shock absorber, distributing pressure evenly across the box walls so your product arrives undamaged even after multiple handling points in transit. All of our materials are tested to withstand edge crush test (ECT) rated for standard UPS/FedEx/USPS handling loads, moisture exposure from temperature fluctuations during shipping, stacking pressure in warehouse and delivery vehicle environments, along with drop and impact forces during automated sorting.
