This is the motherlode category of “stuff”. And in Singapore, there is a LOT of stuff. Please bear that in mind when making charitable donations. If it is not in resellable condition, don't dump it on a charity. Find other channels to freecycle items that are not in great condition.
Note that this excludes electronics. So, for instance, an analogue wall clock is considered a “household item” however a digital alarm clock is considered “electronics”.
