They go by a few names you’ll see across product listings.

• Snaps or snap fasteners: the most common terms.
• Press studs or press buttons: often used for no-sew metal sets.
• Poppers: another casual name for ring- or spring-style snaps.
• Pearl snaps: decorative snaps with a pearl-like cap for western shirts.
• Magnetic snaps: magnets enclosed in caps for bags and wallets.
• Sew-on snaps: metal or plastic halves you stitch to fabric.

On Walmart.com, you’ll find these terms used in titles and descriptions, so it’s helpful to search a couple of keywords if you have a specific style in mind.

Snap buttons create a quick, reusable closure without traditional buttonholes.

• How they work: Most metal sets have a cap/socket on one side and a stud/post on the other; they click together using a ring or spring mechanism. Magnetic versions close via opposing magnets.
• Where they’re used: Shirts, jackets, baby items, purses, wallets, and DIY organizers.
• Why people like them: They’re easy to open/close, low-profile, and can be installed as sew-on or no-sew, depending on the style.

Different styles serve different needs—lightweight sew-on snaps for delicate garments, heavy-duty or magnetic snaps for bags and outerwear. Product pages typically note the intended use and fabric compatibility.

You can often swap a snap with basic tools and care.

1. Identify the type and size: Match the style (sew-on, ring/spring, pearl, magnetic) and diameter noted on your original or the product listing.
2. Remove the old snap: For sew-on, carefully clip threads. For no-sew metal snaps, pry apart gently with a thin tool to avoid fabric damage.
3. Install the new set: Sew-on: hand-stitch through the holes. No-sew metal: use a setter/pliers on a firm surface per the instructions. Magnetic: align polarity and secure tabs or sew-in pads.
4. Test gently and adjust if needed.

Working slowly on a scrap piece first can help. When using tools, follow safety guidance and protect the fabric. For delicate items, a local tailor may be a helpful option.

Common types cover a range of fabrics and projects.

• Sew-on snaps: Metal or plastic halves you stitch on; great for lightweight garments or invisible closures.
• Ring/spring (no-sew) snaps: Press-in metal sets for shirts, jackets, canvas, and crafts; often labeled by size (e.g., 10–15 mm).
• Pearl snaps: Decorative caps used on western-style shirts.
• Magnetic snaps: Strong, easy closures for bags, wallets, and totes.
• Plastic resin snaps: Colorful, lightweight options for baby items and accessories.
• Snap tape: Pre-spaced plastic snaps on a polyester tape for quick closures.

Check product details for diameter, material, and recommended fabric weight to help match the snap to your project.

Choose size based on fabric weight, layers, and how much stress the closure sees.

• Small (about 7–10 mm): Light garments, baby wear, cuffs, or hidden plackets.
• Medium (about 12–15 mm): Shirts, pouches, midweight fabrics, everyday projects.
• Large (about 18–25 mm): Bags, outerwear, thicker layers, or high-use closures. Magnetic snaps commonly fall here.

Also consider material (metal vs. plastic), cap style (decorative vs. low-profile), and any required tools. Product pages usually list diameter and suggested uses; on Walmart.com you can filter by size and finish to narrow choices. If your fabric is very thick, look for sets designed for heavier layers.
