They worked great to fill the tap holes on my wooden kizer collar; They're a little lighter than I'd like, but should stay cold. The 7/8 inch hole was plugged perfectly with it. Also, no color is listed in the description (they looked like bronze/matte finish on the website but they actually came in chrome/shiny silver. I would have preferred a shiny bronze but they also look very nice). The website should be updated with a written description of the color which will deduct 1 star.
