DUNLOP GLASS SLIDE SH/MED

This slide is heavy, in comparison to others that I've had. It is thick and I've dropped it twice without breaking it. It is bigger than than my finger and is bigger inside than the average beer or wine bottle neck. My thumb fits through the hollow of it, if that helps with sizing. But I like it, because I can use it with my Dobro laying flat, or my Guitar in the normal position. This one helps with the beginners pressure on the strings learning.
