This is a very high quality pick, but beware that it is absolutely a pick not for everyone, you most probably will either love it or hate it. I personally don't like it, but that is not important.
I am gonna state the facts now.
This pick is thick and big, texture is "chalky" which contributes to good grip, edges are sharp which means that striking the strings result in a glassy/metal slide feeling and sound, material is easily discolored by the strings.
