Trial before full-size purchase

Travel convenience
The compact, TSA/luggage-friendly sizes and included pouch were cited repeatedly as the main draw for vacations, business trips, and sleepovers.
Brand loyalty / repurchase
Existing UNOVE users bought the kit specifically to carry their established routine while traveling, with several noting this was their second or third purchase.
Pouch/bag appeal
A notable number of buyers said they purchased the set partly or mainly to get the cute, functional pouch, which they reuse for makeup or toiletries.
Gifting
Multiple reviewers bought the kit as a birthday or surprise gift for daughters, mothers, or friends, citing the attractive packaging and trial-size convenience.
