The rubber band is used when connecting two TRAVELER’S notebooks together. It is possible to add up to 4 refills into your notebook but realistically most people use 2 or 3 refills at a time, because using 4 refills adds too much weight and bulk to your notebook.
Since switching out refills is so easy, you may start to realize the infinite possibilities of how you can customize your notebook to suit your changing needs. Set of 4 bands (2 brown/2 black)
