Shopping for leather hardware, patterns & care gets tricky when the project is not yet defined: do you need snap hardware for a repair, a larger quantity for repeated work, or a paper template for a shoulder bag? Among the three fastener kits, compare material wording, finish, package format, included tools, and fabric guidance before price becomes the tie-breaker.
Quick take
The shortlist splits cleanly: P1, P2, and P3 are snap-fastener kits, while P4 is a shoulder-bag pattern. For the hardware, the useful tie-breakers are the named material or finish, package format, included tools, and the stated fabric guidance.
Listed-price comparison
The absolute spread from the lowest to the highest listed price is $21.52.
| Product | Listed price | Price position |
|---|---|---|
| Brass snap kit with 4 tools | USD 10.39 | |
| Metal snap kit with 4 tools | USD 13.45 | |
| 70-set 15mm metal snap kit | USD 12.99 | |
| Leather shoulder-bag template | USD 31.91 |
Decision matrix
- Project type: Snap fastening or repair points to P1, P2, or P3; shoulder-bag pattern work points to P4.
- Listed-price order: P1 → P3 → P2 → P4.
- Fastener tie-breaker: Compare the named material or finish, package format, included tools, and fabric guidance.
- Pattern tie-breaker: P4 is the shoulder-bag template entry, while the other three are hardware kits.
Product notes
Leather Snap Fasteners Kit 10/12/15mm Brass Button Snaps Press Studs With 4 Tool

A reason to choose this kit is the combination of brass button snaps and four installation tools. Its description covers leather craft, canvas, jeans, PVC, mesh covers, jackets, bags, and other listed projects, giving it a broad project scope. The limitation is the mixed-color assortment: bronze, silver, grey, and golden pieces may not suit a design that calls for one consistent finish. The kit is therefore easiest to place when color variation is acceptable and the project needs a tool set alongside the fasteners. For a brass-named snap kit with a lower entry price than the other hardware choices, P1 is the straightforward starting point.
Leather Snap Fasteners Kit 10/12/15mm Metal Button Snaps Press Studs With 4 Tool

Choose P2 when a metal snap kit with four installation tools fits the project. The description lists leather craft, canvas, jeans, PVC, mesh covers, RVs, tarps, jackets, sportswear, and bags, so it can serve several project types. One limitation is the material wording: P2 says metal, while P1 explicitly says brass; shoppers who need brass-named hardware have a clearer match in P1. Its USD 13.45 price is USD 3.06 above P1, creating a concrete cost difference between two kits that both include four tools. That makes the metal wording and project-use list the reasons to select it.
70 Sets 15mm 5/8" Snap Fasteners Kit - Metal Snaps for Leather Craft Repair

P3 suits a project that benefits from a boxed pack and a clearly named 15mm snap size. The description includes a storage box, an installation tool, and four parts in each set, while the fit list covers leather craft, jeans, jackets, handbags, belts, and DIY craft. Its important limitation is explicit: it is for light to medium fabric and not for thick fabric such as wool blankets; some lightweight or worn fabrics should be backed. The gun-black finish is also clearly identified, which helps when that look is part of the design. Choose it for the stated fabric range and organized pack format, not for thick-fabric work.
DIY Sewing Pattern Leather Craft Shoulder Bags Template Pattern Hollowed

P4 is the pattern-led choice. Its title identifies a DIY sewing pattern for a leather craft shoulder bag, and the description calls it a kraft-paper drawing stencil for DIY leather handcraft. That gives the purchase a clear role in shaping the bag project rather than fastening or repair. The limitation is equally clear: the description says template only, so snap fasteners and installation tools are outside this item. At the highest listed price, it sits $21.52 above the lowest-priced kit. Choose P4 when the shoulder-bag template is the deliverable you need; it is not a substitute for a hardware kit.
Final recommendations by use case
- Mixed-color brass snap work: Choose P1.
- Metal snaps with installation tools: Choose P2 when the metal wording fits better than P1's brass wording.
- Light-to-medium fabric repair: Choose P3, whose title and description specify 15mm snaps and whose package includes storage.
- DIY shoulder-bag pattern work: Choose P4.
The shortest route is to decide hardware versus pattern first. Then choose P1 or P2 for the two four-tool kits, P3 when its stated fabric range and boxed pack suit the job, or P4 when a kraft-paper shoulder-bag stencil-not snap hardware-is what the project calls for.
