This 4-drawer storage trolley comes with four 3.9 cm wheels, 2 of which are lockable, ensuring both flexibility and stability. With two half-rounded handles, you can move a full cart of paper or accessories effortlessly with a single hand. The design of the 4 vertically aligned independent drawers makes full use of limited space. Besides, each of the drawers can be removed separately. Therefore, you can use them as separate storage boxes or install them back after collating.
