Read description. I didn't. The kit I received contained 5 mandrels. Not 9 in the picture. So I have to take the blame Because I didn't read the description. However, this seller was misleading with the picture. Lying on the bottom right. I thought I got the set that is in the picture.
Pros
3/16" back plate eliminates the need for lead plate
