THE REFERENCE SHELF
Packaging & buying
Travel size: check quantity, closure and trip requirements
A smaller tube may be more portable, but compare the declared net quantity and the travel rules that actually apply to the trip.
Keep lot details for product questions and official notices
Use the exact product name and identifiers when investigating a concern. A brand-only search is not a full check of an individual container.
Gift sets and multipacks need an item-by-item denominator
A set can contain different products and sizes. Totaling every number on the box can create a misleading unit price.
Refill compatibility comes before a lower refill price
Confirm that the refill is designed for the exact outer container and product. A similar-looking jar is not proof of compatibility.
