A syringe assembly having a flexible and/or slidable flange is provided, wherein in a pre-use or packaged state, the flange is positioned substantially parallel to a barrel of the syringe assembly resulting in the syringe assembly having a smaller packaging footprint. The smaller packaging footprint allows for a reduced storage space of the syringe assembly. Upon removal from a packaging and/or the storage space, the flange can be slid and locked into place such that the flange extends in a perpendicular direction with respect to a longitudinal axis of the barrel of the syringe assembly to allow for a traditional operation of the syringe assembly.
