No. You cannot change the size of any ProMaker button machine. BUT! believe me when I tell you that is an advantage! Being able to remove the dies degrades the quality of the machine. This machine is built for production. It is made to last. removing the dies on button machines leaves them prone to alignment issues and all sorts of other problems. Making a machine for one size only is the way to make a button machine that has zero problems, and will outlast you. Trust me.
