The Tombow Mono Zero eraser is a delightful little tool that packs quite a punch when it comes to removing errors. I have several different retractable erasers, but this one actually looks professional. The classy aluminum finish paired with a rectangular body make it both visually pleasing and easy to handle.

Retractable erasers aren't known for being classy and stylish — in most cases, they're just stuffed into an art case or pencil bag for correcting the inevitable graphite mistake. I wasn't even aware I wanted a stylish eraser until I saw this thing. For less than ten bucks, you get a clean, classy eraser that actually does a great job of erasing.

Tombow Mono Zero Eraser Tip

Given the small rectangular shape of this eraser, you can use the 2.5mm sides or the 5mm sides to tackle different sized problems. Or, if you need an even more precise edge, use one of the four corners of the eraser for that fine-tuned erasing.

One of the first things I look for in a retractable eraser is how well the eraser core stays put when actually erasing. Poorly-designed erasers can be difficult to use because they tend to retract while erasing due to a lack of friction. In the case of the Mono Zero, it has no problems staying put while erasing. This is due to both the low tolerance between the eraser core and the body and the advancing mechanism. The "eraser advancer" operates similarly to a mechanical pencil. Instead of relying solely on a clutch system to advance, retract, and hold the eraser, this eraser uses a plastic rod on the interior to manage these operations. In practice, it works really well.

Tombow Mono Zero Eraser Clip

Each full click advances the eraser by about 2mm, but you can also half-click to advance the eraser by 1mm. The clip on the eraser is much stronger than it looks, and due to the light weight of the tool, it has no problem staying attached to anything to which you clip it. And, since the clip is so strong, you can clip this to the cover of a notebook. The slim profile of the eraser makes this an ideal (and probably intended?) carry option.

As far as branding goes, the Tombow logo and name are printed on only one of the four sides of the eraser body.

Tombow Mono Zero Eraser vs Sumo

I've been really impressed by this little eraser. It's not the most exciting stationery tool one can purchase, but it fulfills its purpose while also looking elgant and classy. If silver isn't your jam, you have a few other color options like black, pink, and blue.

At just under $10, this is a great deal for a retractable eraser that uses metal parts. And, you can also pick up extra eraser cores for just a couple bucks (two erasers per pack), making this eraser sustainable as well.

If you need a retractable eraser that looks great and performs well, look no further. The Tombow Mono Zero is an excellent option.

Sakura Sumo Grip Retractable Eraser Review

When you start delving into the world of pencils, you quickly remember how important erasers are. If you're like me, you probably had an eraser or two in school that looked a little like this:

Pink Pearl erasers

These erasers gave your pencil box a distinctive smell, but I never really thought they were incredibly effective at erasing pencil marks. After working several years at an art supply store, I quickly discovered how varied and focused erasers can be. One of my favorite types of dedicated erasers was the retractable variety, and that's what I'm reviewing today.

The Sakura Sumo Grip retractable eraser is a fantastic design with a soft and efficient eraser core.

On the outside, the Sumo Grip is a long dark gray plastic body with a translucent ruby clip and advancer button. It's understated, but I think it looks pretty cool. It's also pretty sturdy — completely up to the challenge of a messy pencil bag.

Retractable erasers can have some pretty unique eraser advancement mechanisms, but the Sumo Grip is fairly simple. To advance the eraser, simply press the top a couple of times. To use the eraser, just hold the body and wipe away those marks. While some retractable erasers require you to press a button on the side to stay the eraser core, the Sumo Grip has a built in clutch that keeps the eraser from backing into the body. But, if you want to retract the eraser for storage, just press the button on top and push the eraser in for safe keeping.

In use, the Sumo Grip does a great job at erasing pencil marks. I've been trying it with different types of pencils and grades, and I've had fairly consistent results. It performs really well with hard grades, but starts to struggle a bit in the 2B range. It still manages to remove the marks, but it takes a few extra strokes.

According to the information on JetPens, the eraser is made of a micro-porous foam and has certain advantages over other PVC erasers. I don't know much about the different types of eraser materials, but I can vouch for the performance of this particular eraser. With minimal pressure, this eraser can almost completely remove graphite particles from the page with just 3 swipes. In my other tests, going for the complete white out takes just 8 strokes. And, apart from removing the graphite that doesn't belong, it doesn't smear onto the page. It's a clean eraser that does its job well.

The rectangular design (instead of round) gives it a nice edge for making detailed swipes, and the large body gives you plenty of control when making fine adjustments.

Overall, this is a fantastic eraser that I've kept on hand when using pencils. It packs up neatly, does its job well, and doesn't break the bank. At under $4, it's a great deal. You can't order refills, but the entire package is intended to be disposable. You can find other options that offer eraser refills, but this is a great portable option.
