                            I used these on golf towels. They look great, come in several finishes, and perform exactly as I expected.

                            I'm happy with these and all the items I purchase from Kamsnaps. I had a small issue and they went beyond my expectations to resolve it.

                            Limited use for third party grommets

                            Grommet press works very well on Kamsnaps grommets, but will not work on grommets available from local hardware stores. A major drawback

                            Each die set must be custom molded to a specific fastener. Our dies are custom molded to the fasteners we sell. This is why they yield consistently perfect results. Because different manufacturers may make their grommets with slightly different dimensions, it would be near impossible for a single die set to accommodate every variation. Purchasing all components from the same source, whether it be from our store or elsewhere, is recommended and would guarantees compatibility.
