Check the material claim
Separate named materials from vague natural or sustainable language.

"Wood-effect" and "non-stick" hide a lot. Paste the materials or the description and we flag the forever-chemical cookware, the formaldehyde-shedding boards and the VOC finishes, and confirm the honest materials.
