20 Pairs Sew in Magnets, Hidden Magnetic Snap Closure for Thin Fabric ≤ 2mm, PVC Invisible Magnetic Fastener for Bag Lining, Pocket Flap, Clothing Lining

Strong magnets can be easily sewn into an object with a size 14 needle. Will not affect Computerized sewing machines.

I used these magnets to make the closures for several clutch bags. They worked fine and are strong enough to attract through one layer of decent weight fabric. They were easy to sew on my machine & I don’t sew all that often. I would buy these again.

I wanted to use these for theater costuming. Yes, you can sew through the plastic cover each magnet is encased in, but I found that when I put it inside several layers of fabric, the magnet was not strong enough to be relied on. Better for use on things that do not move and have minimal fabric layers. I am not sure I would trust this to hold a purse opening shut.

I am going to make fabric bookmarks & needed them to hold to each other through a page of a book.

In the photo- two magnets between a finger-not that strong. I bought this to help with my husband’s putter cover. It has a thick Velcro part thinking it would be strong enough to cut a slit and insert; it did not work even when I stacked two and inserted, there was a slight stick but not enough to stay closed. Even when I removed the plastic (since I didn’t need it on the inside)This will work on thin fabric but not meant for thick fabric.

Very weak magnets. Tried using these with leather but even through the thinnest leather they would not stick together at all. Maybe for fabric, but even bare they barely stick together. Won’t buy again.

It's a good product

I purchased these to make curtains for our metal doors. These stick very nice.
