One of the things on my To Do Playlist last weekend was mastering this shape. Which I did (squee!), without the use of a press. Each side is marvered smooth with a hand tool, so instead of a coiled look they are a true disk shape with no sharp edges around the holes. Which means they are safe to use with any type of stringing material without fear of the glass cutting it. Sweet.
