Pentel has a wide range of products, even within their mechanical pencil line. Shown above are variations of the Twist-Erase model. I recently reviewed the Twist-Erase Click .9 mm Orange, which I love even more now than when I first tried it, so I was excited to put these to the test.
First up is the Twist-Erase Express .7, Fashion Color Collection. From the package, we learn of the twist-up jumbo eraser, break-resistant lead, and ergonomic comfort grip. Let's dig down into the details a bit further...
Jumbo eraser is no joke - this is by no means an emergency eraser. The eraser can be a bit finicky in that the act of eraser causes the twist mechanism to retract or extend the eraser, depending on which direction you're erasing in. This can be minimized with a firm grip.
The erasing quality was pretty good (yes, I should have done a sample, but I didn't) - the marks are almost completely gone, but the eraser is not quite as good as, say, a Staedtler Mars Plastic. They are, however, readily available at most big box stores, so that's a huge plus.
Final verdict is that these are totally decent, and I think most people would enjoy using them. The colors might not meet everyone's tastes, but fortunately Pentel also makes the same pencil as the Twist-Erase Express, with colors in the 'Office Color Collection'. See below.
Same pencil, just a more mature, more professional look. You'll notice extra leads, an eraser, and four pencils instead of three. This pack is great because it's enough to get someone through a semester or many days at the office.
Again, if you don't mind a lightweight plastic format, then these will probably meet your needs quite well.
Well, it's not just the materials that attract dust; our humidifier was out the week that I took these pictures, so it was uber-staticky around the house. At any rate, you can see the comb-style grip, and the whole package looks a bit 80s perhaps - a bit retro - and I have no problem with that.
I promise that I dust my house - I really do.
Lastly, we have what appears to be a regular Twist-Erase. When I search for the model number of QE515 or QE517, I find the name Twist-Erase III, which is not indicated on the barrel, so I guess this is just another revision?
The bottom line is that if you like lightweight mechanical pencils, and you like an integrated eraser, then there's probably a Twist-Erase model out there for you.
