This magnetic pin dish is not only uber glamorous and shiny - it's magnetic surface is great for throwing pins or other small metal objects into.
Infact, I had my first pin dish like this some years ago when I was gifted one by a student. In those days you only could get boring chrome ones because guess what they really are? They are magnetic dishes made for car mechanics to keep nuts and bolts safe and together! Thankfully someone glamorised them for the sewing room.
They have a non-stick rubber base so they don't slip on shiney work surfaces.
And if you don't have pins you could always use it as a scrying mirror!
