This is a caulking gun kit for the DIY handy-person.
It includes a sealing cap for the tube, an angled tip for extruding a bead of caulk or silicone, a straight and curved extender for getting into difficult places, and push-through cleaners to recover any caulk/silicone at the end of the job.
The cleaners allow most of the silicon in the kit pieces to be pushed out before it can dry inside the tubes, so that everything can be cleaned easily the next day and reused for the next job.
There is hardly any wasted caulk/silicon after the cleaners are used.
Note: The end-cap should be screwed on on top of a folded piece of plastic shopping bag to ensure an airtight seal
