100% Plant oil sealant.  Food safe (can be used on your kitchen utensils and chopping board).
This blend of oils cures naturally through oxidisation and therefore takes a full 4 weeks to cure.  However when it does it hardens to a natural plastic (polymer) and provides protection and prevents colour transfer.  Due to it's 100% oil nature it does not drag the underlying water-based wood stains.
