TWSBI Eco Cracking... A Closer Look

This video was done to simply show a home DIY version of an industry standard inspection method used to check the internal stresses within a part. I am not implying anything regarding the quality of the manufacturing of the pens in this video. I'm simply doing this test to see if anything can be found to back up claims of cracking. I can only speak from personal experience, but I haven't experience any issues with either of my TWSBI Eco pens not my Vac 700R Iris models.
