OXO Good Grips Toilet Plunger and Canister

What is this?

A toilet plunger & holder.

Why did I buy it?

You don't really need a plunger until you do. And it is likely to be a horribly embarrassing situation if you don't have a plunger on hand, ready to go. When people aren't busy clogging your toilets, plungers are also useful for unclogging a kitchen sink as well. 

OXO makes good stuff and it matches the toilet brush I have by them as well.
