Supplier Links

I found a supplier on eBay in the UK. There should be other similar suppliers around the world otherwise purchase some 1.5mm nitrile bonded cork with self adhesive backing and cut out a 30mm disc.

You'll need to punch your own 8mm hole or cut it out with tiny scissors.

Substitutions

Try to avoid normal cork but if its your only option you could try it. A thickness of 2mm is often too much for certain uses so be sure to find 1.5mm thickness.
