These are smaller pieces of virgin cork. These scrap pieces can be used in terrariums for themed motifs or mini mounted displays. Let your creativity go wild! Several bird rescues have purchased these from us as bird chew toys. One bag is filled with random selections of cork, so none will ever be the same. Larger quantities of cork will be sent via UPS ground to save money on shipping cost. This means it will likely arrive after your plants. A bill will be sent to the email address used on your account for additional shipping cost if needed.
