The material seems great for the purpose; I like Tusq picks and nuts as well. These saddles would be great if they came without little edges that need to be filed off, and if they were the right size for a Fender (Japan) bridge. The saddles are too narrow, so there is always some space between them, allowing them to wiggle. Their e-e spacing seems too wide, so they sat on my bridge crooked; pushed by the strings, which were then oblique in the slot (causing some weird extra noises). All in all a great idea, but a bad fit (for me).
