Launch two specification options with small size 19 cm X 31 cm X 23 cm and large size 19 cm X 31 cm X 28 cm to match different cabinet depth demands. Combine thick transparent acrylic panels and stainless steel support rods to form shelf body, install silicone anti slip stoppers to lock basket position during pulling actions. Equip independent separating baffles inside each storage unit to partition internal space and prevent mutual collision and messy stacking of stored items. Reserve matching connecting structures on unit top and bottom to stack up to three sets vertically for upward expansion of total storage capacity. Simplify assembly steps to four support rod connection operations between upper and lower base plates without extra complicated assembly accessories.
