Items sealed and labeled with the required suffocation warning sticker — to Amazon's exact poly-bag specifications by category.
Fragile and delicate items wrapped per Amazon's requirements — preventing damage and avoiding fulfillment center rejections.
Cases packed and labeled to Amazon's carton-level requirements — correct quantities, weight limits, and Box ID labels applied.
