THE CARTRIDGE IS NOT INCLUDED!!! It is only shown in the photo so you can see what it looks like when assembled.  These tablets for the Fluidmaster Flush 'N Sparkle Toilet Cleaning System.  These are NOT the Fluidmaster Brand, but they work just as well with the same basic active ingredient.  Our manufacturer makes these to our specifications using the highest compression available in the industry.  I use these myself and they work just a good as the Fluidmaster Brand.  If you are not into "Fancy and Pretty Packaging" then you can SAVE BIG MONEY!  Wrapped in counts of 6 tablets.  Your choice of 6, 12 or 18 tablets (see our other listings).  We are so sure that you will be completely satisfied with these tablets that we will actual pay the return shipping if you are unhappy for any reason (please see return shipping details in this listing).  IMPORTANT!!! BEFORE YOU ORDER, take a moment to remove the end cap from the cartridge to make sure you can do it.  C arefully pry off the BOTTOM cap of the empty and dry cartridge using a thin flat blade screwdriver. Hold the cartridge firmly while doing this.
The "trick" is to pry the cap by only a very small gap at first (like 1/16" or less) then rotate around 1/3 of a turn then graduate to a DULL knife or larger screwdriver when the gap is bigger, gradually and equally increasing the gap all the way around until the cap comes off.  You will then slip 2 tablets into the cartridge and replace the cap.
