I love these 0.9mm Pentel twist erase pencils.

I have been using Pentel Twist Erase pencils since they first came out in the early 1980s

I've been using the QE 515 Pentel Twist-Erase pens for years.

I'm a huge fan of the higher end Pentel "Twist Erase" pencils, so I figured one with red lead and an eraser specifically designed for that lead would be the holy grail of erasable red lead in a mechanical pencil

My college age daughter very specifically requests 24 pentel twist erase pencils every year for back -to -school

l love these Mech

Nice to find on Amazon as not always available at stores.

Eraser untested as of now.

After having owned these pencils for several months, I noticed the erasers on some of them would occasionally twist out by themselves as I used them, necessitating the need to twist them back several times during a crossword puzzle..
