Nail strengthening and repair
Consumers specifically purchased this product to address weak, brittle, or damaged nails that break easily or peel. Multiple reviewers mention buying it after gel nail removal or as a preventative against splitting and breakage.
Matte finish for workplace suitability
Several buyers valued that the Blue Diaa variant offers a natural matte appearance rather than glossy shine, making it appropriate for professional or casual settings where nail art is not allowed or desired.
Brand reputation and product comparison
Reviewers mention choosing this product after hearing positive reviews or comparing it favorably to other Korean and international nail enhancers, with some noting it outperforms similar products they've previously used.
Small size convenience and gift appeal
The miniature 7ml size with cute character branding made it attractive as a gift or travel item, though reviewers noted this was offset by the high price per milliliter.
Fast drying time
Multiple reviews highlight that the product dries quickly (within 2 minutes), making it convenient for daily application without stickiness or prolonged drying periods.
