Xyron adhesive works so well for adhering things with irregular edges especially. This one is a good size for slightly bigger cut pieces. I don't know what I would do without it.
For me the 510 size has come in real handy with my cuts from the cricut! It is also very versatile- you can buy the repositional& laminating. My only qualm is that the adhesive seems to get used up quicker than I can keep it around. I find I reach for this with almost every altered project. It covers the back of items completely making sure that items do not lift off the page. I just wish they made the adhesive roll longer!
This is a great tool. I use it on my cardstock before I run it through my Cricut and/or Cuttlebug. It makes adding diecuts to my layouts so easy.
