Query: Pilot Needle Point 0.5mm refills

I love this 0.5mm refill for my Dr. Grip pen. It writes a nice fine line---even better than the Pilot Dr. Grip refills that say Extra Fine. I accidentally purchased the Extra fine point refills and they still write a little large. I am so glad I found this Needle Point Refill. I am going to have to order them from Amazon because I can't find them at Office Depot or Office Max now.
