Rigid Magnetic Mailer Boxes
The pinnacle of premium unboxing. Manufactured direct from our specialized rigid converting lines with 1200–1800 GSM solid greyboard cores and concealed N52 neodymium magnetic snap closures. Available in collapsible flat-ship architectures to reduce warehousing freight by 75%.
Solid Greyboard Caliper & Magnetic Snap Tolerances
Unlike corrugated mailers which rely on folded fluting, rigid packaging utilizes solid compression-molded chipboard wrapped in premium art paper. Our automated V-grooving lines ensure sharp 90-degree corner edges with zero bevel distortion.

|---|---|---|---|---|
| 1200 GSM Greyboard | 2.0 mm (0.080") | Dual N52 Rare Earth Discs | 90° Precision Chamfer | Luxury cosmetics, jewelry, small electronics, perfume bottles |
| 1500 GSM Greyboard (Standard) | 2.5 mm (0.100") | Dual N52 Rare Earth Discs | 90° Precision Chamfer | Watches, luxury apparel accessories, premium wellness kits |
| 1800 GSM Heavy-Duty Core | 3.0 mm (0.120") | Quad N52 Magnets (2 pairs) | 90° Precision Chamfer | Spirits & wine gift sets, corporate VIP onboarding hampers |
| Collapsible Flat-Ship Setup | 2.0 mm – 2.5 mm | Integrated 3M Corner Tape Tabs | Foldable Score Lines | High-volume e-commerce brands needing 75% pallet freight savings |
Audible Snap Haptic Feedback
High-flux N52 neodymium disc magnets are flush-embedded in CNC-routed cavities before lamination. Delivers an audible "snap" click and consistent pull resistance that confirms the luxury prestige of your product before the customer even sees the contents.
Collapsible Logistics Architecture
Traditional rigid setup boxes ship as 90% empty air, multiplying ocean container and warehouse costs. Our collapsible V-groove architecture folds down 100% flat and locks into a rock-solid rigid container in under 8 seconds using permanent 3M corner adhesives.
Custom CNC Foam & Velvet Inserts
Complete your rigid presentation with custom high-density EVA foam inserts with precision laser cavities, velvet-topped thermoformed trays, or satin-lined beds engineered to the exact 3D geometry of your bottles, cosmetics, or hardware.

Rigid Magnetic Packaging FAQs
Technical specifications on greyboard densities, magnet ratings, collapsible shipping, and luxury finishes.
Frequently Asked Factory & Manufacturing Questions
Transparent answers on minimums, production timelines, dielines, and corrugated board specifications.
What board caliper and density is used for the rigid core structure?
We manufacture our luxury rigid boxes utilizing ultra-dense recycled solid greyboard (chipboard) available in 1200 GSM (2.0mm caliper), 1500 GSM (2.5mm caliper), and 1800 GSM (3.0mm caliper) thicknesses. Unlike corrugated fluting which has hollow air channels, solid greyboard is compression-molded to deliver an unyielding, rock-solid feel that never bends or collapses under hand pressure.
How do the concealed neodymium magnets function?
Each box features pairs of high-grade N52 neodymium rare-earth disc magnets (10mm diameter × 2mm thickness) embedded directly into precision-milled recesses within the greyboard core before the outer wrap is applied. They remain completely invisible beneath the 157 GSM art paper wrap while delivering an unmistakable, audible "snap" closure every time the lid shuts.
Can rigid magnetic boxes ship flat to minimize freight and storage costs?
Yes. We engineer collapsible rigid boxes with precision V-groove scores and four pre-applied high-bond 3M peel-and-stick corner tape tabs. They ship 100% flat, saving up to 75% on international air/sea freight and warehouse pallet racking, and erect into a rigid 90-degree luxury box on the fulfillment bench in under 8 seconds.
What premium exterior wrap papers and finishes are available?
The greyboard core can be wrapped in 157 GSM coated art paper with anti-scratch matte lamination, soft-touch velvet film, gloss aqueous coatings, metallic foil stamping (gold, silver, rose gold, holographic), spot UV, or genuine textured buckram and linen specialty papers.
What is the production minimum and lead time for custom rigid magnetic packaging?
Because rigid boxes require automated box-wrapping and magnet-embedding machinery, our factory production minimum is 500 units per custom dimension. Production lead time is typically 12 to 15 business days following digital 3D proof sign-off, with pre-production physical prototypes available upon request.
