The invention is a new horizontal syringe storage system for larger syringes which provides a high degree of product safety, storage and accessibility. The horizontal syringe storage system defines offset scallops to provide for tray nesting when stacked in a similar direction and for tray stacking when an upper tray is rotated 180° relative to a lower tray. In use, the upper trays do not touch product in a lower tray. For one embodiment, the syringe storage system comprises raised nubs for vertical alignment between stacked trays. Such raised nubs of a lower tray operably cooperative with the scallop pockets of an overhead tray. This simple feature aligns trays on two axes and limits tray slippage, essentially offering unlimited syringe tray stacking.
