BRUSTRO Electric Automatic Eraser | Ideal for Kids and Adults, Drawing, Sketching, Mandala, Portrait | Slim Battery Operated | 2.3mm, 5mm| 22 Refills, 2 Eraser Holders | (Batteries not Included)

Good working, must buy for beginners

The product is very nice ... Smoothly working on the sheet .... So helpful and amazing purchase

The electric eraser works great and is very easy to use.

From my personal experience,I would recommend you to buy brustro eraser as compared to Derwent eraser as brustro has a slim body,which is easier to hold.Eraser Refills with two different thickness makes it the best product as it can function as mono eraser too.Hence, brustro eraser can fulfill the requirement of mono as well as Derwent eraser at cheaper cost.It is easy to use,no maintenance required and most important doesn't require any special place or storage area, you can keep it anywhere even in your pen stand.There is no shortcoming in the eraser,you just have to clean it with sand paper time to time as particles of graphite or charcoal may deposit on it.Amazon delivers it in the exact shape as shown in reference image and for me there has been no issue regarding delivery by Amazon

this is probably one of the best things i bought. it is so much worth the money and just so easy to use. the best thing is that its very comfortable to hold. perfect length and thickness. i recommend buying this u wont regret ;}

the mechanical eraser works fine but im assuming that the package has been torn for a while and it let air in so all the included erasers are dried out, so they either smear the pencil marks or straight up start ripping fibers out of the paper.

Very good, I would not recommend it for kids though!!

Good
