|Pentel Energel .5mm Needle Tip Retractable Pen|
Ever since I bought my first pack of Energel .5mm pens a few months ago, I was hooked. They write smooth, dark and consistent. The ones I originally bought were the capped "stick" versions but I eventually purchased a box of 12 retractable ones on eBay. The refill will even fit in the Pentel Excalibur RX15! The only real downside I have with the ink is that it is not water resistant. When I was finishing up my final semester of college, I would use this pen to write notes due to the quick drying time allowing me to highlight key phrases without having to wait a lengthy period of time. Pentel also makes the Energel in a .7mm tip, but as of the time of writing this, I haven't tried it. I have some on the way however, so look for that review in the near future. Currently, the .5mm needle tip is one of my favorite pens.
