Review on Permanent Attom Tech Art Oil Based by Hannah Curi

I live at high altitude (6000 feet) so maybe this has something to do with my bad experience with them. In fact, I just poured a teaspoon or more of blue paint on my project - it worked fine for about 20 seconds and then ruined the piece. Black did the same. The greens oozed when I removed the cap so I pressed the tip (tip UP) then turned the marker into a tablespoon and paint almost spilled the entire scoop! The oranges, whites and yellows were completely dry - NO color even got to the felt tip part.
