This women’s leather long wallet with coin pocket OEM case study 02 demonstrates a second-generation product development project at YSK Leather Goods. Where Case Study 01 established the core product, this case shows how an existing wallet design is refined based on customer feedback — adjusting card slot placement, upgrading edge finishing, and adding a zip coin pocket in a more accessible position. A real-world example of iterative OEM product development.

Frequently Asked Questions
What changed between Case Study 01 and Case Study 02 for this wallet?
Three changes based on end-customer feedback: the coin pocket moved from interior zip to exterior zip for faster daily access, the bill compartment was expanded from one to two sections to allow foreign currency separation, and the edge finishing was upgraded from painted to burnished. These are typical refinements we help brands implement when moving from a first-order design to a refined second-generation product.
How do you handle design iterations without paying for full re-development?
We retain your approved pattern files after the first production run. For iterative changes, we apply the revision to the existing pattern rather than developing from scratch. Minor revisions (pocket repositioning, hardware change, edge finish upgrade) are typically free or incur a small revision fee. Major structural changes may require a partial re-sample fee. Most clients’ second-order refinements fall in the minor category.
What is the MOQ for a refined second-generation order?
100 units minimum per style per color — same as the first order. For brands that have validated demand from the first order, second orders typically increase to 200–500 units to benefit from lower unit pricing. We retain all tooling and pattern files between orders at no storage fee.
