Packaging design ("pack-buy")
Many reviewers explicitly say they bought it for the cute keyboard/cassette-tape shaped compact and overall aesthetic, sometimes admitting they hadn't even tried the formula yet.
Personal color / tone matching
Reviewers frequently reference Korean 'personal color' theory (warm/cool, spring/summer/autumn/winter) and choose specific Mood Keyboard editions because the curated palette matches their skin undertone.
Brand loyalty and collecting
A large share of reviewers say they already own other lilybyred palettes and are collecting the series color by color, citing consistently good formula and cohesive color stories as the reason to keep buying.
Influencer/idol recommendation
Several reviews mention buying because a favorite Korean YouTuber or an idol (e.g., Yena) used or promoted the palette in a makeup video.
Discounts and bundled freebies
Purchases were often triggered by Olive Young sales, coupons, or bonus items (mini liner, highlighter, lip balm) bundled with the palette, with several reviewers noting they got it at a steep discount.
