PentelTwist-Erase Automatic Mechanical Pencils - Assorted Sizes and Barrels: QE515A, QE517B, QE519C, 1 for each

Most durable. Easy to hold. Great for sketching or crossword puzzles.

Love them for crossword puzzles, taking notes, anything. The lead is thick enough that it almost writes like a pen. Two relatives ordered them immediately after using mine.

By far my favorite pencils I’ve had mine since high school believe it or not and got these for my kids

There is nothing to complain about! easy to reload, easy to erase, replacement erasers available if you use it up... it's absolutely perfect. i bought these to replace one i had for over 10 years before i lost it.

A well designed pencil with good ergonomics. It also appears to have a durable construction, but time will tell.

These pencils are by far my favorite. They are easy to hold. The lead writes very smooth. And, I love how the eraser twists up instead of having to remove a cap.I gave this particular set 4 stars because the barrel has a barcode sticker (as if being sold individually in a store). These stickers leave a sticky residue. If I want to remove them (and I will) I will have to use alcohol and scrub the stickiness.Its not the end of the world. It's just a nuisance.

Been using Pentel mechanical pencils for years

I had one for decades and decided I love it so much, I need to get more. So, I got the .05, .07 & .09 lead. Couldn't be happier!
