We are now happy to offer easy-to-use Black Plastic Snap Grommets! These grommets measure just over one inch in diameter with the inner opening being a bit smaller than a half inch. These are very simple to use. Just pull them apart (you can use a flat screwdriver or dull knife to pry them apart if necessary). Cut a very small "X" at the area you want the grommet. push the protruding side through the area where you made the cut (it is best if it fits very tightly or even doesn't come all the way through). Then simply press the flat side with the washer onto it until it's firmly in place. The two sides will stay together until you pry them apart. It's that easy! You can use the grommets with the wire kits to create moving curtains. You can use hooks on a rod. You an even zip-tie them! These are very versatile. They come in a package of 10 grommets.
