Fretting about traditional toilet cleaner cages that harbour germs? Fret no more. Duck Fresh Discs Marine have a gel-based formula that self-sticks to the toilet bowl so germy cages aren't something to fret about. Fresh Discs prevent the build up of limescale and germharbouring stains. Just stick one to the inside rim of the toilet bowl so you can keep things clean with a fresh Marine scent. No touching or scrubbing required, just automatic freshening action with every flush. Pretty easy, huh? Starter kit contains handle and 6 gel discs.
