3 Set Electric Eraser, Electric Eraser Kit Battery Operated Eraser Automatic Pencil Eraser with 66pcs Additional Replaceable Rubbers for Artists, Art Pencils, Drawing, Painting, 3 Colors

I love these electric erasers. This was the second time buying these since I lost the set I had before. I love these they work well the battery life is awesome it doesn't wear out the batteries. For the price this time I was happy to see I got three erasers. The extra nibs are two different sizes which helps with drawing. These erasers can be used with the speed of the pressing the button or without pressing the button on manual. Both work so well and offer fine erasing and reverse drawing. Highly recommend if you are into drawing.

Muy útil para realizar brillos sobre grafito.

Really good erasers. They do take a little practice to learn to control them but once perfected they work well

期待以上に使える。細かく見れば本体の組み合わせ部分の粗さ、バリ取りの雑さなど改善してほしいい部分もあるが、コスパ素晴らしい。自分は電池は手持ちのパナソニックの単４のニッケル水素充電池で使用しているがトルクも十分。付属のプラスチック系の消しゴムは紙をほとんど傷めないので製図や素描などにはとても良い。狭いゾーンやスポットで明るくするような時には特に重宝する。色別の本体が3本も付いてくるので、5ミリ径と 2.3ミリ径と各専用で使い分けでき、差し替えの手間がいらないのもいい。

I'm a colored pencil artist and I really like this eraser. The motor is strong and the erasers both thick and thin do not break. It easily removes colored pencil for highlighting and correction. It is important to use a fresh battery and to keep the eraser short to avoid breakage. It is easy to hold and the control button is positioned comfortably. I had bought the Derwent electric eraser but it was awkward and difficult to use. I recommend this product and you get three in a package.
