• Customize our GreenKraft clamshells for your products. Design a custom insert to support your products. Step 1: Mock up Your Design! Order a sample set to visualize your layout. We offer blank inserts tailored to fit each clamshell size. Step 2: Send Them in! Mail your mockup along with your product samples to Sustainable Packaging Industries at 226 W. Ojai Ave STE 101-204, Ojai, CA 93023. Step 3: Finalize.  Upon receiving your mockup and product samples, we'll create a prototype and send you a test copy for your approval. Once approved, we'll proceed to produce the dies. Production typically takes 2 weeks after receiving your final approval. More Info:
