Operational checklist

Print SKU and dimensions on the slot label.

Audit the slot after the first replenishment cycle.
Confirm opening, self-seal behavior, and usable depth before replacing a box.
Use added protection for rigid, sharp, or crush-sensitive products.

Missing dimensions or metrics are called out directly instead of guessed.
Every page links to the canonical Packrift product page and keeps Packrift.com as the commerce source of truth.
