This multipurpose cinch works great. I used to create small books I used the original circle that worked great no problem. I used it on cardstock and also computer paper. I tried the heart punch on the same material and it also worked well on these materials. The heart point at the top worked fine with the smaller wire it may bend the point a little if it’s used with thicker wire. I didn’t have any so I am not sure. Over all it was a good purchase and I plan to use them again.
