Peinture sur papier encadrée

This piece is a beautil painting. It is made with high quality materials, however I only gave it 4 stars because I had a terrrible time trying to get the staples out of the wood frame without damaging it. That didn't happen and I had to touch up spots on the fram before hanging it. Surely there must be a better way to protect the corners of the picture during shiooing? I'm all for using products that are kind to our earth, but in a case like this, styrofoam corners would have been better. Also I didnt use the flimsy, usless hanging kit.
