Dimensional Pairing Guidance

The Sizing Fit Formula: Inserts Meet Containers

A card improperly sized for its outer container risks edge crushing in transit or interfering with self-seal adhesive lines. We recommend balanced interior clearances calculated for real-world automated and manual fulfillment.

SPEC PROFILE: POLY MAILER + POSTCARD FIT
Flat-lay view of an open kraft poly mailer with 4x6 inch thank you insert card resting over folded linen apparel
4" × 6" Postcard ~65% Flat Mailer Width
Recommended for flat goods: allows smooth slide-in without catching outer mailer side seams.
Pairing Recommendation IC-01

Poly Mailer + 4" × 6" Postcard

Compatible Mailer Sizes 10" × 13" or 12" × 15.5"
3D Bulking Clearance Deduct 15–20mm for bulky goods
Adhesive Margin Sits >35mm below seal line
Production Method Offset CMYK + Protective Matte

Balanced for apparel fulfillment. Sizing the card narrower than total bag width allows effortless slide-in packing. When packing bulky items (hoodies, knitwear), ensure bag perimeter expands comfortably without bending the cardstock.

SPEC PROFILE: BUBBLE POUCH + POCKET INSERT
Kraft padded bubble mailer envelope paired with a 3.5x2 inch pocket jewelry care insert card and delicate gold chain
3.5" × 2" Pocket Air-Cell Clearance Checked
Accounts for internal bubble wall thickness to prevent card buckling on entry.
Pairing Recommendation IC-02

Bubble Pouch + 3.5" × 2" Pocket Card

Compatible Envelopes #000 (4" × 8") or #0 (6" × 10")
Cushion Offset Inner usable width is ~15mm less
Recommended Finish Anti-scratch matte lamination
Typical Product Fit Jewelry, Skincare, Tech Cables

Padded mailer bubble linings occupy internal volume. We configure card proportions to slip past cushioned bubble air cells freely, preventing corner crimping when loaded alongside hard small goods.

SPEC PROFILE: RIGID CARTON + STATEMENT INSERT
Top-down view of an open corrugated mailer box with a 5x7 inch gold foil stamped brand story card centered on folded tissue paper
5" × 7" Statement Centered Cavity Proportion

Mailer Box + 5" × 7" Brand Story Card

Compatible Cartons 8" × 6" × 2" or Custom Box Sizes
Rigidity Grade 350–400gsm high-density board
Finishing Harmony Foil tone matches outer carton logo
Application Tier DTC Subscription & Luxury Kits

Engineered as the focal visual greeting immediately upon opening the hinged lid. Sized to leave clean negative space along box edges, resting neatly above products or delicate tissue wraps.

Pre-Production Fit & Volumetric Note: Recommended pairings apply to standard flat envelopes and PackagingAnt packaging lines. Actual insertion clearance depends on product depth, garment folding density, and whether third-party outer mailers are used. Die-cutting follows industry standard mechanical tolerances (±1–1.5mm). We provide 1:1 scale digital dieline templates so you can print mockups and verify physical clearances with your packed merchandise before mass plate-making.

Clear Answers · Zero Ambiguity

Frequently Asked Production Questions

Everything you need to know about multi-design gang runs, dieline verification, and international DDP delivery before launching your production.

Can I split my 500-card minimum order across different designs (e.g., 5 variants × 100 pcs)?

Yes, we fully support multi-variant splitting. You can split a 500-piece order across up to 5 different artwork designs (for example, 100 thank-you notes, 100 care guides, 100 discount cards, and 200 product inserts) under the same 500-tier rate. The only requirement is that all cards share the same outer dimensions, paper caliper, and surface finish. This enables growing DTC brands to launch complete packaging suites without over-ordering single SKUs.

Can I inspect paper stiffness and physical finishes before volume printing?

Yes. We maintain ready-to-ship physical sample packs featuring our 350–400gsm artboards, kraft stocks, hot foils, and spot UV textures. Sample materials are complimentary; while nominal international courier freight applies, 100% of the sample cost is credited back onto your first bulk invoice. Furthermore, we always provide complimentary 1:1 scale digital dieline proofs for vector alignment prior to plate making.

What file formats do you accept, and do you check files created in Canva or Figma?

We accept vector PDFs, Adobe Illustrator (.AI), Photoshop (.PSD), and high-resolution exports. Our prepress team conducts a thorough technical preflight audit—verifying 3mm bleed margins, converting screen RGB into balanced CMYK ink limits, and testing QR code optical scan contrast. (Note: Clients remain responsible for textual copy, pricing codes, and spelling sign-off on the approved proof).

Are customs duties and international delivery fully settled under your DDP quotes?

Yes, under standard DDP terms. For shipments to the USA, EU, UK, and Canada, import duties, customs entry clearance, and commercial doorstep logistics are bundled into your upfront invoice. You will receive tracking via FedEx, UPS, or air carrier with zero surprise import tax bills upon standard commercial arrival.

What is the realistic manufacturing turnaround and transit timeline?

Standard mass production requires 5 to 7 business days following digital proof sign-off. Shipping options include priority express air (3–5 business days for urgent unboxing campaigns) or economical ocean/air freight (15–22 business days) for cost-optimized stock replenishment.
