The punches are made with metal gears and cut through thicker materials like butter. I successfully cut thin chipboard, thick cardstock, and thin copy paper. Here is a video of me using the punches so that you can see for yourself.
After making the video I have been asked, could you use this as a corner punch since it only has 1 bunch. The Answer is Yes, but only if you are careful, since corner guides are not included on the punch, making sure your corners are lined up on all sides can become tricky.
Thanks for stopping in today,
