Olive Young sale discounts
A very large share of reviewers explicitly mention buying because of BIGBANG/olive young seasonal sales or discounted pricing, calling the palette 'a steal' or noting they wouldn't have bought at full price.
Personal color (퍼스널컬러) matching
Japanese and Korean reviewers frequently select a specific shade (Savage Mauve, Sweet Persimmon, Posh Coral, etc.) because it matches their identified warm/cool undertone, a major driver of shade-specific purchase.
Brand loyalty / repeat purchase
Many reviewers state this is their 2nd, 3rd or 4th Espoir eye palette, citing consistent quality and formula from the brand as reason to buy another colorway.
Influencer/YouTuber recommendation
Several reviews cite Korean or Japanese YouTubers/Instagrammers using the palette or mentioning it is used in Korean makeup salons as the trigger for purchase.
All-in-one convenience for travel
Buyers note the palette covers shadow, brow, liner and blush in one compact case, making it appealing as a single travel item, which is cited as a purchase motivator.
