You can now transport your little bag without losing the contents. To open the bag, just pull the tabs apart.
Here's an easy and effective way to manage screws, washers, and other small parts that you need to transport or want to store with the hardware that they belong to. I find it most useful when I'm removing usable parts from broken computer hardware.
So here I am in the office. I've removed the parts I wanted from a broken PSU, but the screws and washers are going to be hard to transport home without a container. I could use a small sandwich bag or a box, but usually I don't have those handy. So I'll use packing tape.
