A novel rack for holding test tubes, elongated objects and the like in an upright position. The rack is formed in a one-piece construction having upper and intermediate panels, both panels having holes which are aligned with one another to receive tubes passing through both panels. The holes securely retain the tubes upright and separate from each other during shipping and dispensing by means of easily deformable holes having integral slits radiating from each hole. The carton is lightweight, collapsible and can be easily scored and recycled.
