Materials and Claim Evidence

Evidence boundaries for product claims

This page separates what the listing says, what we have measured, what is an internal observation, and what remains unknown.

What the listing says

Material, color, sheet count, and scent wording are product or package claims. We preserve the source and date instead of turning them into independent test results.

Paper certification

Bamboo Charcoal, Green Tea and Rose sheet paper: FSC® C232489 · Paper from well-managed forests. This is a certificate-based claim (license code FSC-C232489) for the sheet paper only; it does not extend to the compact case, puff or mirror. Our paper is designed to biodegrade.

What we measure

Our log can cover sheet dimensions, count, single-sheet or pack weight, package dimensions, and one-sheet handling. Every result needs a method, date, instrument, and product version.

What remains unknown

We have not established oil capacity, skin tolerance, acne or comedogenic outcomes, antibacterial or anti-inflammatory effects, wear time, or environmental impact beyond the FSC® C232489 paper certification above.
