What is Aleene's Glitter Snow?

I have had a few people ask me what is Aleene's Glitter Snow? It comes in a little jar and I can only find it when the holiday/Christmas things are out so now is the time you can find it at the craft stores. Michael's, Hobby Lobby and ACMoore I think all have it. It comes in a small jar and I think its like $3. It lasts a long, long time. You brush it on with a paint brush or a q-tip and you use it for snow accents on cards. Its got just a hint of glitter in it and it goes on wet but dries hard, like on this ATC I did (can you see under the monkey?) ...
