Tack Button for a Bag and Luggage Maker in Israel
A Bag and Luggage Maker approached us with a tack button requirement for the Israel market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- An interlining that bubbled after the first press
- A zipper puller that broke under pull test at the warehouse
- Reorders that quietly changed supplier and changed the hand feel
What we specified
| Item | Tack Button |
|---|---|
| Client type | A Bag and Luggage Maker |
| Market | Israel |
| Order volume | 20,000 pieces across 3 specifications |
| Base material | Zinc Alloy |
| Standard size | 50 mm Width |
| Finish | Epoxy Doming |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around Zinc Alloy and locked the tolerance before bulk.
- The finish was moved to Pearlescent Coating after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
Result
- 20,000 pieces delivered inside the 4-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
