Affordable price point
Many reviewers specifically cite the low price as a reason for purchase and for buying multiple colors, calling it one of the best affordable K-beauty eyeshadow lines.
High pigmentation reputation
Repeat buyers say Missha's shadows are known for strong color payoff, which drives them to keep repurchasing the same or new shades.
Wide color range / collecting shades
Reviewers mention wanting 'other colors too' and actively collecting the series, suggesting the 26-shade range drives multi-SKU purchases.
Word-of-mouth / packaging appeal
Some Japanese reviews mention buying based on package design ('パケ買い') combined with positive word-of-mouth reviews seen online.
Regional/limited-edition exclusivity
Several reviewers bought Olive Young-exclusive shades specifically because they were unavailable through official retail channels in their home country (e.g., Japan).
