About this 3D model

The round consumable box features a bi-directional interface, allowing for horizontal and vertical orientation. When not in use, the other opening can be used to store already retrieved consumables, preventing them from winding back and getting tangled. At the same time, the disposable lunch box can be upgraded to a round storage box, providing greater durability. The price is around ten yuan, offering excellent value for money. It also saves space by allowing infinite stacking upwards.
