1. Secure Your Weights
Single weights should be individually wrapped, weight sets need to be secure within their cases and accessories such as milligram covers need to be protected so they cannot move. All weights need to be secure in a container designed to withstand the shipping process. Please remember that clean room cases do not provide suitable protection for shipping and should not be used.

2. Use Proper Packing Material
Single weights should be packaged individually in a vial or pouch or wrapped in acid-free, no-lint paper, then bubble wrap or foam. Weight set cases may also be wrapped in bubble wrap or foam. Do not use packing peanuts—they create static electricity.
