What an awesome pencil.
I bought this pencil less than a month ago to give it a try, since it looked cool. It wasn't until I started using it that I found out it had a shaker mechanism, which is awesome. I've been using it a lot, and just ordered a 0.3 and a 0.7 from JetPens, and the next order will include the light versions to try them out.
My first shaker pencil was the classic Pilot "The Shaker" that I got from my dad (he loves those pencils) and still have it somewhere in my house, but now I've been using mostly drafting pencils, since I like them more, they're good for... well, drafting and graphing, and they're slim enough.
Hopefully my order will be here by Monday or so (yeah, I'm in AZ, so shipping from San Jose is quite fast), still in time for most finals so I get to use them.
Oh yeah, and the guy who sits next to me in Calculus liked it a lot and asked me where did I find it because it was really cool.
And it's 2:40AM, so I'm not making a lot of sense, sorry.
