GTAAOY 100 Sets Metal Snaps Buttons with Fastener Pliers Press Tool Kit Perfect for DIY Crafts Clothes Hats and Sewing, Snap Button Fasteners Kit for Clothing Sewing

First impressions and what’s in the box

I reached for the GTAAOY snap kit for a run of small textile projects: baby bibs, doll clothing repairs, a lightweight canvas pouch, and a couple of shirts that needed new closures. The kit includes an aluminum hand press (pliers) and 100 sets of 9.5 mm metal snaps in 10 colors, with both solid and hollow cap styles. Each snap set comprises a cap, a mating cap (solid or hollow), a socket (female), and a stud (male). The snaps are copper-based, which bodes well for corrosion resistance and long-term color stability.

The pliers are lightweight and compact with a soft, non-slip grip. The press accommodates two die positions—one for setting the socket and one for setting the stud—so you’ll be swapping dies during installs. The kit’s size (9.5 mm outside diameter, 6.5 mm inside) is on the small side, which suits babywear, small bags, pet bandanas, and decorative accents more than heavy outerwear or gear.

Setup and ergonomics

The pliers arrive with removable white rubber dies that seat into each jaw; these cradle the cap and protect finishes while you compress the snap. Seating them correctly matters—if the die is offset, you’ll crush a socket or deform a cap in one squeeze. The handles offer good leverage for thin to mid-weight fabrics. On thicker stacks, I had to bear down noticeably and pay close attention to alignment to avoid skewed crimps.

With plier-style tools, reach is inherently limited; you’ll be working near edges rather than deep into panels. For linings or pockets far from an edge, plan your construction order so you can install snaps before closing seams.

Installing the snaps: the workflow that worked best

Here’s the approach that gave me consistent results:

• Mark placement on both sides while the garment is closed to keep alignment true.
• Reinforce light fabrics with a small square of woven fusible interfacing or a scrap of similar fabric behind the snap area.
• For the cap side, seat the decorative cap in the concave die, place your fabric over the prongs, position the socket on the underside, and press firmly in the socket die position.
• For the stud side, repeat with the other cap and the stud, swapping the die to the stud setting.
• Check engagement before moving on: the socket should snap over the stud with a crisp click, without wobble or tilt.

You don’t need to pre-punch holes; the prongs are sharp enough to pierce cottons and most blends. On tight weaves (duck canvas, twill), an awl helps guide prongs without fraying.

Performance across fabrics

• Lightweight cotton and quilting cotton: Excellent. With a small square of interfacing, installations were quick and reliable. The snap action feels confident without stressing the fabric.
• Knit babywear (interlock, jersey): Good with reinforcement. Without backing, the knit stretches and can distort; a small knit interfacing or tricot stabilizer solved this.
• Fleece: Works with a woven backing. The pile can compress unpredictably, so backing the snap with woven interfacing improves hold.
• Light canvas and twill: Usable, but watch thickness. Two layers of 7–8 oz canvas set cleanly with a deliberate, square squeeze.
• Chambray and lightweight denim: Mixed. One or two layers installed fine; a flat-felled seam was borderline and required more force, with a higher risk of miscrimp.
• Heavy denim and thick seams: Not recommended. The pliers lack the mechanical advantage to set a flawless crimp on dense stacks, and the prongs struggled to bite evenly.

As a small-diameter snap, 9.5 mm has limited bearing area. On thin fabrics, the snap strength can exceed the fabric’s tear resistance if you tug straight out to release. If you’re using these on delicate items, reinforce and teach a “peel” motion to separate the halves.

Snap feel and durability

The copper snaps seat with a consistent, tactile click. On cottons, I measured a firm but not stubborn release—appropriate for baby bibs and shirts. On knits without reinforcement, the snap felt too aggressive and tended to distort the fabric when unsnapped; backing fixed this. The color finishes looked even across the assortment, and after a few dozen open/close cycles during testing, I didn’t see flaking or discoloration.

Incorrectly set sockets will fail quickly, either spinning in the fabric or popping apart on first use. That’s usually operator error—misaligned dies or partial crimp. Once I slowed down and verified alignment, my failure rate dropped to near zero.

Solid vs. hollow caps

The kit includes both solid and hollow (ring) caps. Functionally they’re the same; it’s an aesthetic choice and, in some cases, a thickness consideration. Hollow caps can seat slightly more forgivingly on marginally thicker stacks because there’s less metal to deform, though at this size the difference is subtle. I used solid caps for a cleaner look on shirts and hollow caps on bags for visual contrast.

Limitations and quirks

• Not a heavy-duty tool. The aluminum pliers are purpose-built for small snaps in light to mid-weight fabrics. If you’re installing snaps in leather, heavy denim, or multilayer canvas, a press or larger-diameter snaps would be more appropriate.
• Learning curve on die orientation. The two-position press is helpful, but it’s easy to crush a socket if you mix up which die goes where. A quick test on scrap fabric before the “real” install saved me from mistakes.
• Strong snap action on delicate fabric. Without reinforcement, thin fabrics can stretch or tear while unsnapping. Back the area with interfacing or a small woven patch.
• Edge access only. Typical of pliers, you’ll be limited to placements near the edge; plan your project accordingly.

Practical tips for better results

• Always test on scrap from the same fabric stack.
• Reinforce light or stretchy fabrics with woven fusible interfacing.
• Keep the cap seated flat in the die; feel for full contact before squeezing.
• Apply pressure straight and firm; avoid rocking the pliers.
• If you mis-set a snap, you can remove it by carefully prying up the rolled edge with fine nippers, working slowly to avoid damaging the fabric.
• For kids’ clothing, consider two snaps side by side on stress points rather than one.
• Wipe the dies occasionally to keep debris from marring caps, and add a drop of light oil to the pivot if action feels gritty.

Color assortment and value

Ten colors make it easy to match or contrast with your projects. The finish looks neat and adds a subtle decorative touch. With 100 sets in the box, you get enough inventory to practice and still complete multiple projects without reordering. Because the size is small and the tool is light, this kit feels like the right scale for craft tables and home sewing spaces where you want quick, tidy closures rather than industrial hardware.

Who it’s for

• Hobby sewists and crafters working with quilting cottons, light canvas, chambray, fleece (with backing), or knits (with backing).
• Parents and makers adding snaps to baby bibs, onesies, doll clothes, and lightweight accessories.
• Anyone who wants a tidy, colorful snap without investing in a bench press.

Who should look elsewhere:

• Leatherworkers, bag makers working in thick veg-tan or multilayer canvas, and denim enthusiasts installing snaps through heavy seams. You’ll want larger snaps and a heavier press.

The bottom line

The GTAAOY snap kit is a compact, approachable way to install small metal snaps on light to mid-weight fabrics. The copper hardware looks clean, the color assortment is fun without being loud, and the included pliers get the job done when used within their limits. Success hinges on alignment and fabric choice: reinforce delicate materials, avoid thick seams, and practice on scrap before touching your final piece. Do that, and the results look tidy and hold securely.

Recommendation: I recommend this kit for casual sewists and crafters who need 9.5 mm snaps on lightweight projects and want an all-in-one solution. It’s reliable on cottons, light canvas, and similar fabrics, and the learning curve is manageable with a bit of practice. If your work involves heavy denim, leather, or high-stress gear, skip this and invest in a heavier press and larger snaps; this kit isn’t built for that tier of work.
