Influencer/YouTube recommendation
Numerous reviewers, especially in Japanese and English markets, say they purchased after seeing the product recommended by YouTubers or influencers they trust.
Desire for a true cool-toned contour
Many buyers specifically sought a cool grey shade because most Korean contour products skew warm/orange, and this stick was praised as filling that gap.
Brand trust (espoir)
Several reviewers cite loyalty to the espoir brand or pairing it with espoir foundation/concealer as a reason for purchase.
Repurchase/loyalty
A notable share of reviews are second or third purchases, with buyers calling it their 'go-to' or 'life' contour stick they will keep repurchasing.
Convenience for travel/on-the-go use
Some buyers bought it specifically for its compact stick format as an easy, portable alternative to powder contour.
