We engineer the fit that protects your product.
Custom Box Inserts makes custom-cut foam and die-cut cardboard inserts for the brands and manufacturers who ship things that break, scratch, or shift. Send us your product dimensions, a CAD file, or a photo. Our engineers spec the material, design the cavity layout, cut a sample, and scale it to production. The result is an insert built to your product and your box — not a stock tray you have to make work.
Why We Exist
How we work
QUOTE

APPROVE
You pay only once the design is exactly right.
SHIP
Production runs about three weeks, with rush options for hard dates.
The premium end of a commodity category.
Packaging inserts are usually treated as a throwaway line item. Generic foam, guessed densities, no testing, and a vendor who disappears after the invoice. We built the opposite.
We don’t default to whatever is cheapest on the shelf. We match PE, PU, EVA, or ESD foam and the right board grade to your product’s weight, fragility, and handling — so protection is engineered, not assumed.
We translate fragility and weight into cushioning that survives the truck, the belt, and the last mile. ISTA-informed recommendations and physical samples mean you validate the fit before a full run, not after a return.
Free design help, unlimited proof revisions, and a team that picks up the phone. You work with people who understand inserts, not a form that routes to nobody.
How We Work
Built for the products that can’t arrive damaged.
The same engineered process, tuned to the demands of each category.
ESD-safe foam cavities that hold boards, devices, and accessories without shift and survive parcel handling.
Precise foam nests for instruments and diagnostics, spec’d for cleanliness and drop-test requirements.
High-density foam and double-wall board that carry weight and resist repeated open-and-close in the field.
Printable paperboard trays and clean foam nests that make a set feel considered and arrive unbroken.
Convoluted and routed foam that locates optics, components, and accessories exactly where they belong.
Die-cut board inserts that stage every item on the reveal and keep unit costs low at volume.
