The crayons found in regular supermarkets contain tallow (animal fat). I recently found out that Melissa and Doug company makes vegan crayons, which are non-toxic.
I wanted to double-check, so contacted Melissa and Doug company to find out if the crayons are vegan. They replied quickly and said that "Our crayons do not contain any animal products" .
I'm so happy that I purchased these cute crayons for my toddler. The moment I gave these crayons to my toddler, he put it right into his mouth!
I purchased these cruel-free crayons at Whole Foods. You can also buy it through Amazon or Melissa and Doug website.
