Pentel Ain Clic Knock Triangular Eraser with Clip - Metallic Purple Body

Cool color and the eraser is good. The only thing i don't like is how the eraser sometimes gets sucked back in when you erase too hard. It doesn't stay in place like the Staedlers

I use this erase almost every day. Sturdy, reliable dispenser, holds eraser even with hard or large erasing efforts. It erases well and clean, and with its triangle shape always has at least one good corner to erase with.

This is a nice eraser. Moms...your kids need this! It is comfortable and erases completely. Plus it comes in cool colors!!!

I want to like this eraser, but a couple of flaws keep it from being a favorite.
The triangular shape should allow precision erasing, but once you've worn a corner down, the precision is lost. After a few erasures, you're left with a big round eraser.
The mechanism doesn't hold the eraser in place well, so direct pressure will push the eraser back into the body. Side-to-side is okay, but combined with the above, it loses the precision the triangular shape could deliver.
The eraser itself is good, not abrasive at all, and very effective. I don't find the shavings to be sticky or hard to brush off, and HB markings are 98% removed. If the clutch could hold the eraser in place better, this could be perfect.

Wonderful!!
I purchased a few of these erasers about a year ago and have had fantastic luck with them. I've since tried the other erasers shown here at JetPens but none compared really. They actually hold up. All the other stick style erasers I've tried all back into the tube when you try to use them (I'm a little heavy handed) but these Ain erasers hold up remarkably well. I completely recommend!
