[DoingSomeThings]

Seconded. I buy 2 varieties of Muji pens -- 0.38 and 0.5 Gel Ballpoint -- and stash them everywhere.

A while back I heard the phrase "If you ask 'where is the good XYZ' it means you have a 'bad' XYZ". I was inspired to throw out all of my cheapo pens and always have a good one nearby.

Same with power cables, scissors, tape, and other small household accessories. They're too cheap to have to worry about 1. where they are and 2. where the "good" one is.
