1+1 promotional pricing
Many buyers explicitly say they purchased because of Olive Young's 1+1 (buy-one-get-one) deals, citing it as excellent value for a consumable/accessory item.
Influencer recommendation
At least one reviewer cited seeing a YouTuber (minsco) recommend the wide, thick elastic band for people with heavy hair volume.
Repurchase of trusted brand
Multiple reviewers say this is a repeat purchase, trusting Fillimilli's tools generally after positive experience with other items in the line.
Need for a strong, damage-reducing elastic
Buyers with thick or long hair sought a band that could hold hair for hours without snapping or pulling too tightly, and reported this one met that need.
Free-shipping threshold filler
Several Japanese reviewers bought it specifically to reach the free shipping minimum, then were pleasantly surprised by the usability of the band and cutter.
