Natural vs Expanded Cork
Our granules are natural cork, not expanded cork. Natural cork is denser, stronger and far more versatile. It holds its shape, doesn’t break down easily, and provides a stable, consistent material for substrates, mixes, fillers and craft use.
Available in kg bags, with larger trade and pallet quantities available on request.
All orders are supplied directly from our UK warehouse for fast, reliable delivery.
