I  picked up a STAD pencil extender from Jetpens last week and as my usual  review style, I put it through it’s paces before I wrote a review.
 
I’ll  admit my first impression was not good. Looking at the package I was  expecting some weight and this extender while chunky is very light  weight. I tried stuffing a vintage FaberCatell Design 3800 4B into its  grasp and the little white plastic cap didn’t like it, or the extender  didn’t like it, whatever it was the pencil is now in hiding and I can’t  find it. (Turns out it was just hiding lower in the pencil cup…) Every  pencil I stuck in it’s jaws seemed…. Loose. 
 
I  took a look at the back of the package. There were some diagrams on the  back with all the writing in Japanese… Picture #3 shows some fingers  touching the jaw. I thought maybe in that image the fingers are  squishing the jaws to the pencil, so I tried it. Oh baby, what a  difference. The extender went from loose to thighs of steel. It grips  all my regular sized pencils, from my Palominos to Vintage FaberCastell  Design 3800s to PrismaColor Col-erase with an eraser. 
 
 
 
When  you are done drawing or writing you can flip the pencil point into the  extender and protect the point from breaking and you from being stabbed.  WIN! This holder, like others, allows you to use your pencil down to  the last tiny nubbin. The smooth grooved barrel is comfortable to hold and use. It's diameter makes it seem as if you are writing with a nice mechanical pencil or pen. Fancy.
 
(Protip:  When you get down to the end of your pencil, use a sharpie to write the  hardness on the top of the pencil so you always know what pencil nubbin  you’re using.)
I purchased the STAD one touch pencil extender for my own use. Jetpens did not compensate me for my review.
