Great question! Depends on the size and weight of your product. Our website: www.arka.com has mailers and shippers. Mailers are E flute with a description for what’s best for those and Shippers are B flute respectively. We’ve gone through tons of trial and error so you don’t have to in determining what’s best for your product! For more questions go to support@arka.com and thanks for messaging in!
