Pentel Twist-Erase UP Mechanical Pencil (0.5mm), Lime Barrel, Box of 12 (QE105K)

These are not as sturdy as other Pentel Twist-Erase pencils but a decent buy for the money.

would not recommend for regular use or for serious students. this pencil is cheaply made, especially for a pentel product. in contrast with the picture, there is no metel barrel at the lead site.

I ordered these pencils for my 4th, 5th and 6th graders and more than half of them were jammed or falling apart within an hour. They are flimsy and very poorly engineered. Avoid!
