Magnetic Closure Boxes — Manufacturing Guide
A magnetic closure box uses embedded neodymium or ferrite magnets to hold a hinged lid shut. The closure is silent, requires no ribbon or tuck flap, and can be opened one-handed — which is why it dominates beauty, jewelry and electronics gift packaging. Production lead time is {{X}} weeks after artwork approval, MOQ from {{Y}} pieces.
Magnet specification — what actually determines the feel
| Parameter | Common range | Effect on the box |
|---|---|---|
| Magnet type | Neodymium (NdFeB) / ferrite | Neodymium: thinner, stronger, higher cost |
| Diameter | 6 mm – 15 mm | Larger = stronger hold, needs thicker board |
| Thickness | 1 mm – 3 mm | Must be ≤ board thickness minus wrap allowance |
| Quantity per box | 2–4 (typically 2 front, 2 side) | More magnets = more resistance, harder to open |
| Pull force | {{X}}–{{Y}} N | Above {{Z}} N most buyers find it too stiff |
| Board thickness | 1.5 mm – 2.5 mm | Magnets must be fully concealed inside the board |
The most common specification error: ordering magnets that are too strong. A closure that requires two hands feels premium in a sample and irritating in daily use. If you cannot test physically, specify the lower pull force first.

Magnet safety note: small magnets are a choking hazard and are subject to restrictions in some markets. If your product may reach households with children, tell us at brief stage — we will specify encapsulated magnets and document it.
Frequently asked questions
What is the MOQ for custom magnetic boxes?
{{MOQ}} pieces. Magnet insertion is a manual step, which is the main reason MOQ is higher than for folding cartons.
Can the magnets be replaced by velcro or hidden snaps?
Yes, though the hand-feel differs. Velcro is audible on opening; hidden snaps are cheaper but lose tension after repeated cycles.
Will the magnets interfere with electronics inside?
For most consumer electronics, no — the fields are small and localised. For medical devices or magnetic storage media, tell us and we will specify ferrite shielding or reposition the magnets.
Are magnetic boxes recyclable?
The paper and board components are. The magnets must be removed before the box enters a fibre recycling stream and are themselves recyclable as metal. Design the magnet pocket so it can be located and removed — we can mark it on the inside wrap.
