As far as labels go, I bought a package of white mailing labels 1 inch by 2 and 5/8 inches at Dollar Tree. I printed: This lunchbox belongs to and This backpack belongs to and my daughter's name. Then I put the label on cardstock and cut it to the size I liked. I placed Disney Princess stickers around the label. I then laminated the label and use a hole punch to make the hole. My husband found some metal rings like for key chains and I put the label through the ring and then put on her backpack or lunchbox. It works great because it won't get messed up because it is laminated.
You can also get lamination done at Mardel for super cheap. I think is only 25 cents for quite a large piece.
