Please make sure that you message me with any questions regarding this item.  I am not sure if these cut out dies will work with any other badge machine besides the Badge-A-Minit 3".  They cut a circle of  3 1/4 (3.25) inch and are strong enough to cut through vellium as I show with my own machine.  Great for all sorts of crafting projects.  Very heavy machine weighing 15 pounds of sturdy steel to last decades.  The bottom of the machine has four rubber feet also keeping it very secured and sturdy.   This machine is strong and sharp enough to let you multi-cut up to six layers of computer paper with  one pull of the handle!
