How to Use Chroma Rivet Snap Magnets 18mm for Bag Closures

Learn how to install Chroma Rivet Snap Magnets 18mm as a secure bag closure. This guide covers the parts, preparation, and step-by-step assembly without guessing missing steps.

What You Get in a Chroma Rivet Snap Magnet Kit

Each Chroma Rivet Snap Magnet 18mm set includes the parts you need for one closure: two rivet caps (12mm), one male snap magnet (18mm), and one female snap magnet (18mm). The snap magnets are the magnetic halves that hold your bag closed, while the rivet caps are decorative covers that hide the rivet heads on the outside of the fabric.

The magnets are available in six Chroma finishes: Red, Purple, Blue, Pink, Orange, and Green. Choose a color that matches or accents your bag's exterior.

Preparing Your Bag for the Snap Magnet

Before installation, decide where the snap will sit on your bag flap and body. The 18mm magnet diameter needs a hole large enough for the magnet post to pass through. Typically, you'll mark the center point on both the flap and the bag front, then create a small slit or punch a hole just wide enough for the magnet stem.

Because the supplied product information does not include exact hole sizes or recommended tools, use a sharp awl, hole punch, or small scissors to make a clean opening. Test the fit with the magnet before proceeding.

Assembling the Chroma Rivet Snap Magnet

The following steps assume you have prepared the holes in your fabric. Work on a flat, protected surface.

  1. Insert the female magnet: From the wrong side (inside) of the bag flap, push the post of the female snap magnet through the hole. The magnet face should be on the outside of the flap.
  2. Attach the rivet cap: On the outside of the flap, slide one rivet cap (12mm) over the magnet post. The cap covers the rivet head and gives a finished look.
  3. Set the female side: Using a rivet setting tool or a hammer and anvil, gently tap the rivet cap to secure it onto the magnet post. The cap should be flush with the fabric.
  4. Repeat for the male magnet on the bag body: Insert the male snap magnet post from the wrong side of the bag body, then attach the second rivet cap on the outside. Set it the same way.
  5. Test the closure: Once both sides are installed, bring the flap down so the magnets meet. They should snap together securely. If the magnets don't align, check that both parts are centered and the rivet caps are fully seated.

Important Considerations Before You Start

The supplied product information does not include official installation instructions, so the steps above are based on common practice for rivet snap magnets. If your bag uses thick or layered fabric (like canvas or vinyl), you may need to pre-punch the holes or use a stronger setting tool.

Also note that this product has a processing and shipping time of 6–8 business days, not including the date of purchase or transit. Base shipping starts at $10.99, and overages over $2 will be refunded. Plan your project timeline accordingly.
