My favorite cheap shipping "coffin" for razors up to about 13/16. I have squeezed a few 7/8 razors in them. Cheap and fairly strong. I can roll a razor up in a zip lock with a dessicant pack, stuff it in one of these cases, and drop it in a padded envelope and be fairly certain that it will slip through the mail without being destroyed. The beneficiary can keep it or toss it. it's job is done once the customer takes out the precious.
