Oh the reminder that our brain can change. This is our neuron totebag and our dendrites are continually changing, they develop spines, they grow, they retract. Keep those neurons active and take this bag along with you. The dark colors will help to camouflage any hitchhiking dirt that your massive studies and intellectual endeavors attract. It measures 15 inches in height and 13 inches in width which is the perfect size to carry your books or groceries, gym clothes etc.
