Product safety labeling varies by item, but many coloring kits are marked non-toxic and show an age recommendation (commonly "ages 3 and up"). Some items also include CPSC choking-hazard warnings for small parts.
Most kids' colored paper is uncoated or matte. Some cardstocks are specifically labeled as matte, while construction-style colored paper is typically uncoated.
Many colored cardstocks are described as compatible with inkjet, laser, and copier printers. Separately, some marker-and-paper sets use special mess-free paper where colors appear only on the matching paper and not on skin or clothing.
