200 Sets Grommet Tool Kit,1/2 Inch Grommet Metal Eyelets + Washers, with 3Pcs Grommet Setting Tools for Fabric,Tarp,Canvas,Bags,Curtain,Leather(Gold, Silver)

The grommet material is too thin and should have a larger outside diameter. The result is that the grommet does not hold onto the material as well as needed. Using two flat rings instead of one helps a little...still not good. Also, the hole punch should be sharp, but it is not. Easy enough to fix it you have a grinder but there is no reason not to make it right in the first place.

I had to do all the work, cut the fabric then wrestle onto grommet then hammer over piece - cutting piece in kit WORTHLESS !!!
