Yikes! Color us concerned.
Unfortunately, the 36-count Playskool crayons sold by Dollar Tree were tested and found positive for trace amounts of Tremoline, a kind of Asbestos, which is a known carcinogen that can lead to serious health conditions, including cancer. However, the crayons have not been officially recalled by the FDA.
Also, it appears a Dollar Tree spokesperson said that the crayons had passed all of its legal and safety requirements but did not mention whether the items would be officially recalled. Stay tuned for more information, if these crayons are officially recalled then returning them to your local Dollar Tree Store for a refund might be an option.
