A vacum sealer would work, but be a little bulky. I would think that a good wrapping in one of the clear plastic wraps would get the job done. <br><br>In my work I used to carry yellow lumber crayons in my bag. In the summer they would get hot and melt, making a big mess. A simple solution was to rubber band two of them together. Don't know why, but that pretty much stopped the melting. I don't know if that would work with gule sticks or not.<br><br>I have used a glue stick to mend stuff. Just melt the end with a match/lighter, drip the stuff on whatever you want to mend, then press the parts together...
