Ok ladies I realize most of you probably don't travel with your colored pencils, but I discovered something today that I did not know. This is the first summer I have had prismas before that I had cheap ones. Well prismas in a hot car all day, the wax will melt out of the pencil tips into your pencil bag. Makes sense but it didn't dawn on me until I saw it with my own eyes. I mean I always take care about certain items in my stamp bag to be brought into the store with me while I am working and not leave in the car but I hadn't thought about my pencils. It didnt' ruin my set thank goodness, just made a real mess in my bag, but I think if they had been out there longer it could have been much worse, so thought I would share that they don't take the heat well.
