One of my previous bosses "dipped" so he had all of these cute little tins. I asked him for them, so he gave me quite a few. I use them to separate my different types of straight pins (the ones that I have in small quantities) and write the content on the edge with a magic marker. They are so useful!
I also use those flip up type gum containers for safety pins, etc.
I love to "recycle" for my own use!
