Let's talk about these magnetic snaps – they're a bit of a rollercoaster! I've used them in multiple projects, and here's the real tea.
The good? They're incredibly easy to sew in place. The PVC coating makes them simple to handle, and they don't require any extra embellishments to look decent. I've successfully used them for interior closures on bibs and lightweight handbags where the fabric layers were minimal.
However – and this is a big however – don't believe the 'super strong' claims. Through two layers of even thin fabric (cotton + flannel in my testing), the hold becomes disappointingly weak. They work okay for decorative closures but fail as functional fasteners under any real tension.
Durability seems decent though! One set survived an accidental 30-minute dye bath (not recommended, but good to know they can handle moisture). The magnets maintained their strength after this unintended stress test.
Pro tip: If you're using these for kids' items or costumes where quick changes are needed, they perform adequately. But for serious bag closures or thick fabrics? Keep looking. Also, that color-coding (yellow=positive, silver=negative) is a lifesaver during installation!
Final verdict: 3/5 stars. Great for light-duty, decorative uses where strong hold isn't critical. Manage your expectations accordingly.
