I am so glad to have discovered a source of small magnets in Australia. I use them often in my sculptural work as they allow me to attach my lightweight sculptures to their bases in a way that allows for movement and change. This particular order of tiny 4mm x 2mm discs was for a large flock of 30 corellas made of recycled plastic wrap. I wanted to be able to fix them to their steel bases in a way that allowed them to move very slightly in the air currents to simulate a flock of corellas feeding on the ground. They are perfect!
