Press-on product information observability datasets

Two small, non-representative page-level datasets documenting whether selected public press-on nail product and sizing pages expose predefined information fields. Version 1.1.0 contains 16 records and 160 recorded checks. The data measures information observability only and does not establish product truth, quality, safety, fit, performance, compliance, popularity or market-wide prevalence.

Commercial interest: The author is Jin Bai, founder of NAILINK. NAILINK operates in the press-on nail category discussed by the datasets.

Source exclusion: NAILINK pages and products are excluded from the recorded sample.

AI assistance: AI tools assisted with data preparation, validation and documentation. Jin Bai remains responsible for the released data and interpretation boundaries.

Independence: This is an author-owned dataset. It is not independent editorial coverage, peer review, endorsement, a customer review, product testing, clinical evidence or a compliance assessment.

Limitations: The sample is small, selected and non-representative. Page-level captures may change. A visible field does not establish that the information is true. The data cannot support claims about product quality, safety, fit, performance, compliance, popularity or market share.
