Why Custom Box Inserts
A perfect fit, from prototype to production.
Send us your product dimensions, a CAD file, or even a photo. Our engineers design the insert, cut a sample, and scale to production once it’s right — no guesswork, no wasted runs.
Free design proof in 24–48 hours
We turn your specs into a CAD proof and cut layout at no charge. Unlimited revisions until the fit is exactly right.
Foam or cardboard — the right one
Shock-absorbing foam for fragile and high-value goods, or recyclable die-cut board for retail and e-commerce. We spec what your product actually needs.
Built for real supply chains
Drop-test guidance and ISTA-informed cushioning so your product survives the truck, the belt, and the last mile.
Order sizes that fit your run (25 to 100,000+)
Prototype one, run a thousand, or scale to full production. Volume pricing that improves as you grow.
What We Make
Two ways to protect your product
Whether you need cushioning foam or clean, recyclable paperboard, we cut inserts that fit your product and your box exactly.
Custom Foam Inserts
CNC-routed and die-cut foam cavities that cradle each item. Ideal for fragile, heavy, or high-value products.

“Send the product and the box. We engineer the fit.”
How It Works
From spec to shipped in four steps
Four steps from your product dimensions to a fully engineered insert program.
Share your specs
Send dimensions, product weight, and box size — or upload a CAD file or a photo. No file? We’ll measure from a sample.
We design it — free
Our engineers propose the right material and cavity layout and send a CAD proof within 24–48 hours. Revise free until approved.
Approve a sample
We cut and ship a physical prototype so you can test the fit and protection before committing to a run.
Scale to production
Approve, and we produce and deliver in 7–10 business days on a schedule that fits your line. Rush options available.
