How to Design Custom Magnetic Cartridge Boxes: Sizes, Inserts & Finishes
Custom magnetic cartridge boxes are an attractive option for brands looking for a premium packaging presentation.
However, successful packaging design involves more than adding a logo to a rigid box. Dimensions, insert construction, magnetic closure placement, printing, and surface finishes all affect the final result.
This guide explains the key decisions to make before ordering custom magnetic cartridge packaging.
1. Start With the Actual Product Dimensions
The first step is to measure the products that will go inside the box.
For 510 cartridges, confirm the actual length, diameter, and any protective components. If your packaging includes multiple cartridges or accessories, measure each item separately.
A magnetic box designed for a single cartridge may require a completely different interior structure from a multi-piece kit.
When planning dimensions, consider:
- Product length and width
- Number of pieces per box
- Insert thickness
- Required clearance
- Opening direction
- Overall box proportions
Avoid relying only on labels such as "1ML" or "2ML." These describe cartridge capacity, not necessarily the physical dimensions.
2. Choose the Right Magnetic Box Structure
Rigid magnetic boxes can be developed in different shapes and opening configurations.
A book-style magnetic box offers a familiar opening experience, while other flap arrangements may be more suitable for specific product layouts.
Consider how customers will open the package and how your team will place products inside during assembly.
The magnetic closure should be positioned so the lid closes properly without interfering with the insert or product.
3. Paperboard Inserts vs. Foam Inserts
The insert plays an important role in both presentation and product positioning.
Paperboard Inserts
Die-cut paperboard holders are useful for brands seeking a clean, coordinated packaging appearance.
They can be printed and designed with custom compartments for cartridges and accessories.
Foam Inserts
Foam inserts are suitable when products need a closely fitted arrangement.
Custom cutouts can be developed for individual cartridges, accessory sets, or different product shapes.
The best choice depends on the product geometry, desired presentation, handling requirements, and budget.
4. CMYK or Pantone Printing?
Printing is another important decision.
CMYK printing is commonly used for full-color graphics, gradients, and detailed artwork.
Pantone spot-color printing may be preferable when a brand requires more precise color matching across packaging batches.
Actual color appearance can still vary with substrate, surface finish, and production conditions.
For color-sensitive projects, request a physical proof or approved production sample when appropriate.
5. Select Premium Finishes Carefully
Magnetic boxes can incorporate decorative effects such as:
- Soft-touch lamination
- Matte or glossy lamination
- Spot UV
- Raised UV
- Foil stamping
- Embossing and debossing
A combination of foil stamping and raised UV can create a distinctive result, but their placement needs to be reviewed.
Overlapping effects, fold lines, and structural edges can introduce production limitations.
A carefully planned finish often looks better than adding too many effects to the same surface.
6. Consider Packing Efficiency
Packaging should be practical for the team handling the products.
Before production, evaluate how easily cartridges can be inserted, whether the insert stays in place, and how much space the completed box occupies during shipping.
Rigid magnetic boxes are generally shipped assembled, so carton dimensions and freight volume should be considered when planning a large order.
7. Review Samples Before Bulk Production
A pre-production sample helps verify:
- Overall dimensions
- Magnetic closure function
- Product fit
- Insert arrangement
- Artwork positioning
- Surface finish appearance
Confirming these details early can reduce the risk of changes during bulk production.
Conclusion
A successful magnetic cartridge box combines premium presentation with a practical structure.
By confirming product dimensions, choosing the right insert, and reviewing printing and finishes before production, brands can create packaging that looks professional and works efficiently.

FAQs
What information do I need to design a magnetic cartridge box?
Product dimensions, number of pieces, preferred structure, artwork, insert requirements, and estimated quantity are a good starting point.
Are magnetic cartridge boxes available in custom sizes?
Yes. Both the exterior dimensions and interior insert arrangement can be customized.
Can magnetic boxes include foil stamping?
Yes. Foil stamping can be applied to suitable surfaces, with artwork and structural limitations reviewed before production.
Are standard magnetic cartridge boxes child-resistant?
No. A magnetic closure alone does not establish child resistance. Any child-resistant claims require an appropriate design and applicable testing.
