I got this for my dog's paw print, but he wouldn't let me do it, I tried multiple times over a few months so the ink ran out. He passed away a few days ago, and the vets managed to get his paw print with the bare ink remaining. It's really easy for anyone to use and clearly lasts a while if you're making multiple attempts. I only wish I had purchased another one to get more prints for my family, but we managed to get it photo copied
