Kokuyo Kado-Keshi Petit Eraser, Set of 2, Pink/White (Keshi-U750-2)

The main reason why I bought this eraser is because my handwriting is so tiny and I always need the corners of the eraser and I thought this one is perfect for that. But the erasing quality is seriously not good, it leaves trails of the letter erased and also smudges so it's not really good. I give it a 3-star review for the sake of the shape and supposed functionality

It does its job. The concept is pretty interesting! It might be different with a bigger version of this, but holding and handling this small version sometimes is uncomfortable... The eraser itself isn't super high quality compared to other Japanese erasers on the market too.

These are the best erasers out there for erasing in tiny boxes that you might find in cross-word or Sudoku puzzles, degree plans, order forms, or when precision is required in a line drawing. Not only do these erasers have massive amounts of corners and straight edges, they are made from the finest vinyl eraser material that makes minimum waste, saves your paper, and also doesn't expire after a few years like rubber does. I heard about these erasers on Peter Barakan's Japonology series. Apparently these erasers have made their way in to museums of good product design, and I can see why. I bought some in Japan and now have to resort to Amazon and eBay to buy them for my friends and co-workers. The best size is the full-size, however, which is sold solo.

I gave these erasers to my son in law and oddly enough they started a mini argument in my daughter's home. Apparently she can never find erasers in her home because her husband takes them to school (he is a school teacher). So, maybe I will have to get her another set for home (or him another set for school - I never saw how that settled out). The multiple corners make this a great eraser for little tight spaces. And maybe go ahead and get 2 sets so there is no fighting over them.

I ordered the blue/pink set. They work well, and are a good companion for pencil boxes/cases. The smaller size (approximately 1" or 1.5") is convenient to travel with, but can be lost easily. They work about as well as flat erasers, but the multiple corners are a nice feature. I wish I had a larger version, but these are a nice novelty. I imagine they will last me a long time.

Very cute and small! Erases cleanly and the perfect size. A bit squishy when pushing opposing corners, so that's a bit fun. The only bad part was the price :/ but they're so cute and they seem like they will last a long time, so I don't mind. They also have plastic coverings around them within the package...I don't know if that's for holding the shape together or for protecting it when you're not using it, but it seems like a nice little add-on.

Too small. My daughter has another brands Kadokeshi eraser which is twice the size of this one about 1.5inches long, and it really works well, however Kokuyo kadokeshi is tiny, each cube is even tinier. You have to be careful when erasing or gets damaged from erasing back and forth.

Perfect for sudoku and crossword puzzles!

小学生の子供用に買ったのですが、算数の時に角度など細かい所を消すときは、とても使いやすいと言っていました。

I am a student in college and I'm always erasing things with corners of erasers. I love Japanise stationary and this is the most fantastic eraser I've ever bought. I would highly recommend this!

スケジュール帳の記入や、事務仕事の際の細かい欄の書き間違いの訂正の際に便利そうなので購入してみました。キュートな透明ケースに入っていてそのかわいらしさに文房具好きなわたしのテンションが上がりました！実際使ってみると、角がたくさんで細かい場所が消しやすく便利ですが四角い消しゴムをくり抜く形で角を作っているので強度がなく、ケースから出しすぎるとグネグネと折れて使いにくいので、ケースから少しずつ出して使っています。角っこを使うと丸くなってくるので、調整しながら消しています。。笑丸くなりすぎると、新しい角が使えるので新品感覚を何度も味わえて、個人的には気に入っています。

細かいところは消しやすいです。（当たり前ですが･･･）その反面大きいところは消しにくいです。（当たり前ですが･･･）なので他の普通の消しゴムとの「併用」をオススメします。

The erasers are extremely small, and that's what I wanted. However, the quality of the eraser is rather poor and not as hard as I'd like. (The squares of the puzzle falls off easily)
