Packaging & keychain design
An overwhelming number of reviewers say they bought the product because of the adorable shell/madeleine-shaped case and the bundled silver keyring or charm, often calling it a 'pakebuy' (package purchase).
Mocha/trend shade chasing
Several buyers explicitly mention purchasing because they couldn't get the popular 'Freshian Milky Mocha' shade and wanted a similar mocha-toned cream blush.
Brand loyalty / repeat purchase
Multiple reviewers say they buy 'all NAMING products' or repurchase because previous shades or other NAMING base items worked well for them.
Gifting
A few reviews specifically mention buying the product as a gift, citing the cute case and keychain as gift-appropriate.
Collecting multiple shades
Many customers bought 2 or more shades at once (or plan to buy 'all colors') because the packaging and subtle color variety encourage collecting behavior.
