Un-Du is found at Michaels or Hobby Lobby or a scrapbook store. That's how I found it! Our local SBS owner had some and I found it amazing! It took pictures off that I had glued on in the wrong place and didn't harm the pictures. I got brave and took some pictures out of my dad's scrapbook that he kept while he was in Korea. I took out the telegram that he got telling him I was born! It didn't hurt a thing! I love that stuff!!!
