Sakura Crepas RBE300 Electric Eraser, Battery Operated, Yellow

Much cleaner erasure and stronger torc than cheaper erasers in the market. With this eraser, it will keep spinning with harder pressure, while the two $10-range erasers could only handle light pressure. Originally got the black & red colored Sakura Sumo Grip which is by the same maker but couldn’t resist getting a more colorful model from overseas Japan (you guys reserve the best designs for yourself!)The erasers easily sharpen to a point for finer detail if you wear it down at an angle. You can do this on sandpaper but I find that even with normal erasing this is possible.Just a note, the blue eraser is the higher performance model compared to the yellow one hence it is more expensive ~$10 more. Both are highly functional. They are pretty similar but I was able to do a side by side comparison and found the blue one erased slightly cleaner, vibrated less in the hand but had a higher pitched sound/faster spin when on. In the details the blue one is supposed to have about 4 hrs battery life while the yellow has 1.5 hrs. I thought the yellow one was cute but once I saw the difference I ended up keeping the blue one. However, they’re both great and you can’t go wrong with either.I’ve tried 2 other cheap electric erasers found on Amazon (~$10) and they can’t even compare. The buttons required more pressure to press, but the torc was not as strong and required a light touch to continue running. You are paying for quality and longevity with the Sakura Crepas eraser. The rechargeable version of this brand is used at Studio Ghibli and I can see why! It is an indispensable tool and makes drawing on pencil much more enjoyable knowing I can erase with a quick light touch instead of smudging and over-erasing my lines with a traditional eraser. It feels almost like digitally erasing a line because you can erase almost instantly with little effort.Last of all, Sakura manufactures several eraser refill types that can erase pencil, drawing/drafting ink, toner ink and more. The blue model (RBE400) Sakura eraser comes with a sample of 4 eraser types. This is the only brand I currently know of that provides multiple types of erasers for their electric eraser. I bought two boxes of refills with 60 pcs each, the normal white eraser for pencil and a light gray one for ink (500B-N). I was amazed the first time I was able to erase ink. The ink eraser does sand down the paper gradually to get rid of ink, and it does it very gently. I was able to get rid of ink smudges fairly easily, and the eraser did not cause holes or visible tearing in the paper, although if you ran your hand over the paper you can tell it was slightly worn down. For darker lines the process was slower.I quite enjoy this eraser and hope to use it for a long time.
