Shopping for leather hardware, patterns & care can split into two very different jobs: choosing closure components by size and finish, or choosing a template that sets the shape of a bag. The useful shortcut is to decide whether you need mixed snap sizes, a defined 15mm quantity, or a crossbody pattern before comparing prices.
Quick take
The Leather Snap Fasteners Kit with brass snaps offers the broadest listed size range, while the metal snap kit has the same diameter choices and four installation tools. The 70 Sets 15mm Snap Fasteners Kit is aimed at a single diameter with boxed storage, and the Leather Craft Bag Sewing Pattern Set is for a semi-circular crossbody bag project rather than fastening repairs. Listed prices span $9.82, from $10.39 to $20.21.
Listed-price comparison
| Product | Listed price | Price bar | Decision cue |
|---|---|---|---|
| Leather Snap Fasteners Kit - Brass | USD 10.39 | Brass snaps, mixed 10/12/15mm sizes | |
| Leather Snap Fasteners Kit - Metal | USD 13.45 | Metal snaps with four installation tools | |
| 70 Sets 15mm Snap Fasteners Kit | USD 12.99 | 70 sets, gun black, storage box | |
| Leather Craft Bag Sewing Pattern Set | USD 20.21 | Kraft paper crossbody bag template |
Decision matrix
- Several snap diameters in one kit: The brass snap kit and the metal snap kit both list 10mm, 12mm, and 15mm choices, so they fit projects where the closure size is not yet fixed.
- A defined 15mm format: The 70 Sets kit keeps the choice to 15mm and adds a storage box, making its format easy to identify for a repeat repair or accessory project.
- Material wording is the deciding detail: The first snap kit explicitly names brass, while the second uses the broader term metal in its title and attributes.
- Building a bag from a template: The Kraft paper pattern set is the relevant choice for a semi-circular crossbody design with sewing holes.
Product notes
Leather Snap Fasteners Kit - Brass

At $10.39, this is the lowest-priced entry and covers 10mm, 12mm, and 15mm snap sizes in one mixed lot. The brass button snaps and four-color mixed presentation suit a project where you want several diameter choices or varied finishes rather than a single size run. The package includes installation tools and is listed for leather, canvas, jeans, jackets, bags, and similar craft work. Its limitation is the mixed sizes and colors, which can be less convenient when one consistent snap specification is the goal. Choose it for range; choose another kit when uniformity matters most.
Leather Snap Fasteners Kit - Metal

At $13.45, this metal snap kit keeps the 10/12/15mm size range and includes four installation tools. It suits leather, canvas, jeans, PVC, mesh covers, jackets, sportswear, and bags, so it fits projects that move across several materials. The round snap format and mixed-lot packaging give it a practical role when you want multiple listed diameters in one kit. Its limitation is less material specificity: the title identifies the snaps as metal rather than explicitly naming brass. If brass is the deciding material, the brass-named Leather Snap Fasteners Kit is the clearer match.
70 Sets 15mm Snap Fasteners Kit

For a project built around 15mm snaps, this $12.99 kit supplies 70 sets in gun black and includes a storage box plus a snap-installation tool. Its listed fit covers leather craft, jeans, jackets, handbags, belts, and DIY craft, making the format easy to match with repair or accessory work. Each snap set has four parts: two caps, one stud, and one socket. The limitation is its stated fabric guidance: light to medium fabric, with thick fabric excluded. It is a sensible pick when quantity and storage matter, but its single listed diameter narrows the choice for mixed-size projects.
Leather Craft Bag Sewing Pattern Set

At $20.21, the Leather Craft Bag Sewing Pattern Set is the pattern-focused choice here, built around a semi-circular crossbody or casual handbag project. The Kraft paper template is described as a sewing stencil with holes, and laser precision cutting is listed as part of its introduction. That makes it the natural direction for someone planning the bag shape before cutting and sewing leather. Its limitation for hardware shoppers is that the set centers on a pattern rather than snap components. Choose it for a crossbody bag build; it does not replace a fastener kit when the task is repairing or adding closures.
Final recommendation by use case
- For mixed-size closures and explicitly named brass: choose the Leather Snap Fasteners Kit - Brass.
- For mixed-size closures with the broader metal designation: choose the Leather Snap Fasteners Kit - Metal.
- For 15mm repair or accessory work with 70 sets and a storage box: choose the 70 Sets 15mm Snap Fasteners Kit.
- For a semi-circular crossbody bag sewing project: choose the Leather Craft Bag Sewing Pattern Set.
The main decision is therefore straightforward: select the snap kit according to diameter range, material wording, or set quantity, and select the pattern set only when the project starts with a bag shape rather than a closure.
