Here’s my video on the 300 series. In this one I quickly cover the entire series (500, 600, 400 & 300, and included the 800).
This was an interesting video to make. Halfway through editing it my friend over at HeroTV Stationery mentioned my channel on his review of the 500. It was perfect timing so right after I mentioned the 500 in my video I was able to promote his channel. We are both trying to get viewers from each others respective countries, and are trying to help each other out with that.
I have a “fix” for the lead hardness indicator- but, there was another weird synchronicity - again, with perfect timing. I was just wrapping up my final editing and saw This post on Reddit. Basically it shows you the proper way to use the lead hardness indicator.
Spoiler alert 
: there is nothing wrong with this pencil, we just were not using it correctly.
So anyway I was able to add this at the last minute, but I also left my “solution” - which now in hindsight I highly recommend that you do not do.
I’ll make this public tomorrow- I put my “solution” at the end and advised people to stop watching if they are short on time. But if you do watch until the end, i do show you the pencil with the lead tube fully removed from the pencil body.
Anyway - check it out and let me know what you think!!
