Jackson & June Polymer Clay Cutters are 3D Printed with PLA. The cutters are designed with a tapered .4mm edge to provide both sharpness and resistance to sticking. Size listed is the long side. All cutters are made to order and will be shipped within 10 business days. For more info, see our Cutter Info page linked in the menu bar.
My sizing opinion: .5 in for studs and 1 in - 1.5 in for dangles.
