<< They are just big oil crayons that they mark cattle with

These are great! I thought I was the one who discovered them!! They are very
inexpensive and not as messy as oil pastels because they develop a "skin"
after a while. They also do not come in the large variety of colors that
other art supplies come in, but they are certainly worth a try to check them
out. I know nothing about their longevity or chemical makeup so check for
info on toxicity before using them in your classroom.
