Renewable Quercus Super (or Cork Oak) is grown on the Iberian Peninsula in planted groves. The interior surface of the bark is impermeable and antimicrobial making these safe for use around food.  These characteristics also make cork oak ideal for use outside in the garden where it will weather to a silvery patina. These would make a very unique gift for a gardener or an outdoor enthusiast.
