  Slightly misleading,..., April 10, 2009
By todavecave - See all my reviews
Slightly misleading, the eraser is actually only 5mm wide, not 10mm. Unless they were talking about the tube itself which just seems odd. If you notice the print at the top of the tube says medium which means there probably is a large version that has a standard 10mm eraser in it. Would be fantastic if Jet Pens carried it!

Soft eraser, easy to erase slim lines, dark lead tends to build up fast on the eraser and smudge so I recommend using a harder=lighter pencil lead 2H-4H if you want to use this eraser regularly. Solid construction, simple mechanism, I like the fact it is see through and that you get a good amount of refills for a fair price...

I am an engineering major, and naturally I'm doing a lot of math all the time. This is great for fixing all those little mistakes. The eraser quality is much better than other similar erasers. Mine gets used a lot as my go to pencil is a kuru toga and we all know the erasers on them aren't worth...

I use this eraser a lot since I use a Kuru Toga and those erasers are so tiny I would have to buy a ton, because I erase quite a bit. Good price and the refills are also at a good price. This is a great eraser.

  great idea. I want to..., August 16, 2013
By jimterry - See all my reviews
great idea. I want to like this eraser because of the design and size, but, as another reviewer pointed out, the female threads on the clear end where the black tip screws in have cracked. This makes the tip very loose, the eraser just recedes back into the body when you try to use it. I have though about trying to glue the threads back together so I can use the rest of the eraser. I have not abused this product.... I think it is just inferior plastic that was used. Won't be buying again -at least until the product is upgraded or something.

Will jet pens replace this item?
