On demand Toilet Brush Nib

We are all familiar with the ubiquitous toilet brush. Yes, that bristling monster that sits (doth sit , or hath sat (for those enraptured by third person pluperfect)), putrifying in its own (or more specifically, our own) detritus.
Several recent attempts to resolve this most horrific of situations have given us the "disposable" toilet brush. Neatly packed, and dare I say it, hermetically sealed, nibs, that we position on an elongated applicator.

Trouble is, a six pack of aniti-microbial bliss is just that; a six pack of anti microbial bliss.
Bog roll, to colloquially name the beast, on the other hand, is packaged in packs of twenty four, and seldom runs out. Given its usefullness in cleaning the arse, and adjunct areas.
Given the oragami folding abilities of better-day machines (insipred by [Paper Money Origani folding Machine]) we could have a mechanism that dispenses nibs for a given applicator. The dispensed nib attaches to said appplicator. The nibs cleans. The nibs flushes with the offending article/s. Viola! Applicator doesn't run out of nibs. A forever-clean repository.

Or, in the interests of brevity, "A fucking toilet cleaning nib, created from an existing source (namely the bog roll), not seperately purchased, that cleans the dunny and dissolves away."
