Sakura SumoGrip Block Eraser - Microporous Erasers for School, Drawing, and Writing - Black Color - Large Size B300

Bought as a gift for a professional machinist, tool & instrument maker, hobbyist mechanic & tinkerer, who also regularly uses skills in carpentry, metalworking, and all sorts of DIY things you’d expect from someone with a barn-sized garage workshop full of cars, tools, and machines. He said it’s the best eraser he’s ever used. Pretty solid endorsement?

Works great! Doesn’t smear!

I love this eraser. It lasts more than 1 full school year. Wish they brought back the clickable version. Erases cleanly and doesn't break easily.

used this for mechanical pencil writing. This digs in pretty good.

I was skeptical! I purchased this for colored pencils. I wish they made it in a super skinny version! It’s an amazing eraser and one of the best I have purchased. It’s big and bulky, but amazing! The reviews are legit! It’s as good as people say 😁 💯

This works perfect for all my calculations and graphing but not so much on my drawings. I'm not entirely sure if its the paper (though it's never pilled or ripped it) or if it's the type of lead used. It works on my Pentel and Ain-stein lead fine but it has problems with my pencils. My only other complain is that it's really big for my hand so it can tire me out. I used to buy the sumo grip eraser that used to come in a rectangular pen with the click top but sadly they discontinued it and the mini versions of this eraser cramp my hand and on occassion rip easily which is more than a little frustrating. I'm tempted to cut this into thick strips but don't want to ruin the whole of it. #studentproblems

This eraser works very well. I highly recommend it.

The sumo black foam erasers have become my favorite. I prefer the pen-style long rectangle version, but this will be very useful for large areas. They're gentle on paper but remove marks from my Blackwing drawing pencils well. Definitely try these out if you sketch!
