Pentel Twist-Erase III Automatic Pencil

My first one of these was obtained for free - I found it in a parking lot. Score! It's the model that uses 0.7 mm lead. After using it for a full day of writing I liked it so much I paid my own money to buy this two-pack in 0.5 mm, which is what I generally use. I then gave my supply of Pentel Quicker Clickers to my teenage son - my old hands really appreciate the added comfort of the Twist-Erase III's thicker body and rubbery grip. I can't speak to what others are receiving, but I bought from Office Depot via Amazon (look at "seller" to see who you're buying from - it's not always who you'd prefer) and received a blister pack with two pencils (I got black and blue, FWIW) with two eraser refills. The pencils were each pre-loaded with a full-size twist-up eraser and one stick of lead plus one in the chamber. The ones I received have been very reliable, as I've come to expect from Pentel. The one I found in the parking lot had been at least lightly used, but probably not run over given its wear marks, and is now onto a new life in my hands. I also bought a green one because I wanted something other than black (I couldn't be sure I'd get a black/blue combo in the pack), and that one is superb too. Now, the TIP FOR POCKET CARRY... the cap of a Sharpie fine point (not the extra fine) permanent marker fits perfectly, and the rubber grip on the pencil makes a solid, even airtight, seal. No more holes in pockets or bags! Uncapped, the pencil (with the eraser retracted) measures about 5-1/2". With the cap lightly but securely fitted, it measures about 6", but if I jam the cap on, it's just 5-3/4". When writing you can use the pencil's clip to hold the cap, use the cap's clip to attach it to your work, or just set it aside (its clip keeps it from rolling away). I tried the cap off a Bic permanent marker of seemingly similar size, but it didn't fit. So if you have a half-dead Sharpie lying around, you can salvage the cap. Added bonus: now you have a clip at both ends, and the sleeve is protected. Your second bonus for reading this review comes from my teenage son, who was thrilled to be handed down my Quicker Clickers. He shared his way of quickly advancing the lead on top-click mechanical pencils. He just sort of quickly jabs the eraser (non-pointy) end of the pencil into his chest. That way, you don't have to change hand position to advance the lead - you can write almost uninterrupted. I've adopted this technique, and it works great. Old dog, new trick.
