I buy bags and cases for a living — EVA molded shells, electronics organizer bags, hard shell watch travel cases, travel makeup bags, first aid pouches. Six years, roughly $280,000 a year in accessories and hard-goods spend, and a spreadsheet of vendor quotes I am mildly embarrassed about.
These are the questions I get asked most often, plus one that nobody asks and probably should. Short answers. No fluff.
1. Two vendors quoted the same EVA molded case and one is 40% cheaper. What am I missing?
In my experience it is almost never labor. It is the material spec that nobody wrote down. The low quote quietly assumes a thinner shell wall and a standard nylon zip; the higher one assumes a heavier wall and a molded pull. At 3,000+ units that difference alone can eat most of the gap.
The second silent variable is tooling. If one quote amortizes a mold across the run and the other does not, you are not comparing the same offer. One of them plans to bill you later, or is reusing an existing mold they did not mention. Ask in writing: is tooling included, and who owns the mold?
2. Who should own the mold?
You, if you are paying for it. I am not a tooling engineer, so I cannot speak to cavity design or steel choice — that is a conversation for the people actually cutting it. From a procurement side, though: get mold ownership and transfer terms in writing before the PO goes out, not after.
Tooling quotes in our files ran from roughly $1,500 for simple single-cavity work up to $8,000+ for more complex multi-cavity molds, based on quotes we collected through Q4 2024. Don't hold me to those figures — tooling pricing moves with complexity and I have maybe a dozen data points, so treat it as a range, not a rule.
3. What MOQ should I actually care about?
The number in the email is rarely the number that matters. What matters is how MOQ stacks. A vendor says 1,000 units — great, until you learn it is 1,000 per color, per size, per insert configuration. Order four colorways of a watch travel case and you have committed to 4,000 pieces, not 1,000.
So when I evaluate a custom protective case program, I ask for the MOQ matrix, not the MOQ headline: minimal per SKU, whether shell color changes reset it, and whether logo method (pad print vs. deboss vs. woven label) has its own minimum. I have walked away from two vendors purely because that matrix was a mess.
4. How do I tell whether a vendor will actually hit the lead time?
Ask for production dates, not lead-time promises. Anybody can write 25 days on a quote. What I want is: when did this exact SKU last run, and can I see three past ship dates for it? A supplier with a real production history answers that in an hour.
Honestly, I am still not sure why some vendors consistently beat their quoted dates while others consistently miss by a week. My best guess is internal buffer practice — the reliable ones quote pessimistic and build slack, the others quote optimistic and hope. The surprise for us was not the price gap on a Nintendo Switch hard case program. It was that the higher-quoted vendor shipped about nine days earlier on average across six POs, which more than paid for the premium.
5. Do I need to worry about freight on cases?
Yes, and more than on almost anything else we buy. Cases are mostly air. A cowboy hat hard case, a PS5 carrying case, a hat storage case — these are volumetric nightmares. You are paying dimensional weight, and on bulky shells freight can easily reach 15–25% of landed cost. On a small travel cosmetic bag or an earbud carrying case with a low unit price, freight can be a bigger line item than the product.
Two things I do now: ask for carton dimensions and units per carton before I approve any quote, and calculate landed cost per unit including freight instead of comparing FOB. Rates shift constantly, so verify current numbers with your forwarder rather than trusting mine.
6. First aid kits and trauma kits — same bag, right?
No, and this is where buyers get quiet and then panicky. On the bag itself — a bag first aid pouch is a straightforward sewn or molded item. But the moment you are sourcing a basic 1st aid kit, a compact first aid kit, a complete kit or a trauma kit, you are buying contents, and contents carry labeling, expiry and classification questions.
I am not qualified to advise on medical device classification or regulatory claims, and I would be cautious with any supplier who volunteers that they are. That is a compliance conversation, not a procurement one. What I can tell you is what to demand from the vendor: a full bill of materials with item quantities, expiry dates and lot tracking on anything perishable, whether contents are assembled in-house or repacked from a third party, and what is printed on the outer label. Get the BOM in writing and have your compliance team read it before you sign.
7. What is on your pre-production checklist?
Eight things, and I do not skip any of them anymore. A twelve-point checklist I built after our third rework is the cheapest insurance we own — it has saved us an estimated $8,000 in potential rework over two years.
- Approved golden sample, dated and signed by both sides
- Material spec sheet with wall thickness and fabric weight in numbers
- Hardware and zipper brand/grade specified
- Packing spec: carton size, units per carton, polybag and desiccant
- Logo placement drawing with tolerances
- Drop and compression test method agreed up front
- Pre-shipment inspection booked before production starts
- Written confirmation of who pays for what if quality fails
Five minutes of verification beats five days of correction. Most of the problems we have hit were visible on paper before the first unit was cut — thinner walls than specified, a substitution on the zip, a label in the wrong position.
8. What is the question nobody asks?
What happens to my design if we stop ordering? Buyers fight hard over unit price and then hand over a custom case, a personalized makeup bag or an OEM laptop bag design with no restriction on reuse. Then two years later they see something very similar in a competitor's catalog.
Ask for tooling and design ownership, a no-resale clause on your specific configuration, and written limits on how long the supplier can hold your artwork. Our current case supplier, Chfine, itemizes tooling as a separate line and confirms ownership in the quote — I wish every supplier did, because it makes the conversation short.
None of this is glamorous. But the deals that hurt were never the ones where we negotiated too hard. They were the ones where we assumed.
