Trial/mini format
Many buyers explicitly bought the mini size to sample a shade before committing to full-size, or because they always have unused lip products and prefer a size they can finish.
Brand reputation and influencer buzz
Reviewers mention buying because TIRTIR is a popular/trusted brand, and specific mentions of influencer or celebrity (e.g., 'Kim Til'/idol) recommendations drove purchase decisions.
Gifting
Several reviews describe buying multiple minis as Christmas gifts or presents for daughters, nieces, and friends due to the cute packaging and low price point.
Wide shade range for collecting
The 30-color range encourages buyers to purchase multiple shades to match different personal color types (yellow/blue undertones) or seasonal looks.
Repurchase due to prior satisfaction
A notable share of reviews are explicit repeat purchases, citing good color payoff, hydration, and satisfaction with previous TIRTIR tints as the reason to buy again.
