How to Specify a Custom Magnetic Closure Box (Size, Board, Insert)
A custom magnetic closure box is specified as a system: the shell, the magnets that hold the lid, and the insert that stops the product moving. If any one of those is guessed, the sample will look finished and still fail in use.
This is a specification note, not a catalog. The type range is Magnetic Boxes. Jewelry programs that use this opening are on Jewelry Packaging. Broader gift formats without a magnetic lid are on Gift Boxes.
Size from the product, then the lid
Measure the item or the set, including any tray or pouch that must travel with it. Add the insert wall and the wrap, not only the product outline. Say whether the lid should open fully flat, stay hinged, or fold for a collapsible empty box.
Foldable magnetic constructions exist so empty boxes ship flatter. They still need a fit review when the product is heavy or off-center. A necklace that sits well in a rigid lid-and-base can slide in a collapsible shell if the insert is a flat card instead of a well.
Do not send “small / medium / large.” Send millimeters. If the product is still in tooling, send the current CAD or a photo with a ruler and say the size may move. That is more useful than a locked number that will change.
Board, wrap and closure
Greyboard gives the rigid feel. The wrap is the print surface. Magnets are placed so the lid meets cleanly without a gap you can see from the front. Magnet count and board caliper are confirmed on the sample against your product weight and lid size. This page does not publish a catalog magnet spec.
Ask for a white sample before print if the lid span is wide or the product is heavy. Print hides a gap; it does not fix one. If you need foil or emboss on the lid, mark the safe area so the magnet well does not sit under a thin foil plate that cracks when the lid flexes.
The insert is part of the box
A magnetic box without a located cavity is only a shell. Paper, cardboard or molded-pulp inserts are cut from the product. For rings, chains or small sets, the insert is usually the first thing to approve after the outer size. If the same shell will hold more than one SKU, say so before sampling so the cavity plan is not rebuilt later.
Jewelry buyers should say whether the piece ships on a card, in a pouch, or bare. Skincare sets should list every bottle. Chocolate trays should lock cavity count before foil. Those details belong in the first brief, not in a comment after the printed sample.
What to send with the inquiry
- Product or set dimensions and a photo
- Whether the empty box must fold flat
- Insert need: fitted tray, simple card, or undecided
- Print and finishing references (foil, emboss, soft-touch only if required)
- Quantity range and destination market

Collapsible magnetic boxes and inbound cube
If empty boxes ship from Shenzhen to a filling warehouse, ask for a collapsible magnetic construction and write the flat size you can accept. The jewelry, skincare and chocolate examples on Magnetic Boxes use foldable or collapsible closures. That is a freight decision, not a decoration decision.
If the box is packed once at the plant and never opened until the customer receives it, a non-folding rigid magnetic shell can be simpler. Do not pay for fold-flat hardware you will never use.
How sampling usually runs
A useful path is white structure first, then print. Confirm that the lid closes without a visible gap, that the insert holds the item through a short shake test, and that the empty box folds if you asked for a collapsible construction. Only then approve color on the actual wrap paper.
If you skip the white sample to save time, you often spend that time later on a printed lid that does not meet. Lead time and MOQ stay on the quote. They are not listed as a site-wide promise on this article.
Why Choose Jiayi Packaging
Magnetic-closure work is a structure job before it is a print job. Jiayi Packaging develops foldable and rigid-feel magnetic boxes in Shenzhen for jewelry, skincare and chocolate examples already shown on the Magnetic Boxes page. The same plant lists ISO 9001, ISO 14001, FSC and related certificates on Factory.
The reason to brief this factory is that the insert and the lid can be sampled together. A trading desk that only forwards a pretty render cannot tell you why the magnet gap appeared.
FAQ: custom magnetic closure box
Are magnetic gift boxes the same as gift boxes?
No. Gift Boxes is the presentation range. Magnetic Boxes is the closure type. A gift format can use a magnetic lid; the full magnetic range should be specified on the magnetic page.
Can every magnetic box fold flat?
No. Foldable constructions are specified when empty inbound cube matters. A non-folding rigid magnetic box may be simpler if the box is packed once at the plant.
Do I need foam inside a magnetic jewelry box?
Not by default. Paper or pulp inserts are the first path on this site. Foam is a different material review. Say so if a retailer requires it.
A practical next step
Lock size, lid behavior and insert before you argue about foil. Send the brief through Contact and ask for a white magnetic sample against the live product.
