Stability above everything the PP plastic sheets are tightly locked in place by quality ABS connectors for firm support, allowing each shelf to hold up to 5 kg of clothes or shoes. Two anti-tip straps are included to give your collection a safe perch. Honestly, the assembly of this cube organizer is as easy as building blocks. Simply insert the panels into the slots of the connectors, tap with the included small mallet, snap the hooks with a click, and fix the dividers as needed. You will finish it before you know it.
