Well, we took on the adventure of lip balm. Actually been experimenting for a while now and seem to have a receipe that works for us. Does anyone else use the shrink wrap sleeves over the tubes? We are looking for suggestions to shrink it down. Yesterday we used the ol hair dryer trick, but it is a long process, not very user friendly, and I can see replacing the hairdryer every couple of months doing it that way. Any help is greatly appreciated!!
