The clear 2x3 self seal plastic bags are perfect for any aspect of jewelry making. I can fill the bags with individual bead styles and have them ready when I start a project. It's a great help that I can write the style & size of the beads on the outside of the bag. Because I've already placed them in bags, if I need to pick up and go, I can easily put them in a carry case and take and make my jewelry anywhere...in the car, on the plane or at a friend's house. These bags can also be used for so much more. I use them in my every day life to help keep everything organized. I'll admit, I'm a little OCD, so I like to have everything in its place and easy to grab. They are the perfect size for paper clips, nails and screws, etc. The bags are a great size for traveling when you need to hold just the right amount of shampoo & conditioner, cotton balls, bandages, etc. I like to use them for seperating all of my many different earrings, rings, delicate necklaces and small pendants. It makes it so much easier to see exactly what I have at a glance. I can pack my outfit, with the selected jewelry, and place them together in my suitcase and I'm ready to go!
