    06 · FAQs

    Magnetic boxes, answered.

    The questions we get on every quote call. If you have a different one, just ask — a real packaging consultant replies within 2 hours.

    What's the minimum order for magnetic boxes?

    +

    50 units for standard rigid sizes. For collapsible magnetic boxes, we can begin with just one box. Digital prototyping is available for ultra-short runs.

    How fast will I get my quote?

    +

    Within 2 hours during business hours. A real packaging consultant — not a chatbot — reviews your brief and replies with pricing, options, and clarifying questions.

    Can I get a physical sample first?

    +

    Yes. Free material samples (un-printed) ship within 3 days. Paid pre-production samples of your exact box ship within 7 days.

    Do magnetic boxes ship flat or assembled?

    +

    Standard rigid magnetic boxes ship pre-assembled. Collapsible magnetic boxes ship flat to cut your inbound freight cost by up to 70%.

    Are the magnets safe for shipping electronics or food?

    +

    Our standard recessed magnets are food-safe and electronics-safe at typical strengths. For magnetic-sensitive products, we offer non-magnetic snap or ribbon closures.

    How long does production take?

    +

    Standard turnaround is 8–10 business days from approved artwork. Rush production compresses this to 6–8 days.

    Do you charge for design or dielines?

    +

    Never. Free design support is included with every order — dieline, digital proof, and revisions until your artwork is press-ready.

    What file formats do you accept?

    +

    Print-ready PDF/X-1a is preferred. We also accept .AI, .PSD, .EPS, and high-res .PNG. Our team flags any production issues before press.
