The Derwent USB Rechargeable Eraser is an extra fine eraser. It is ideal for fine hair-line erasing or for adding in highlights on detailed artwork or technical drawings. This eraser erases quickly and precisely in a non-abrasive, circular motor movement. The function button is easy to switch on and off as required, allowing your hand to hold freely for maximum control over your artwork. It is suitable for left and right hand use.
The USB Rechargeable Eraser comes with a built-in 500mAh Lithium-ion battery which holds a long lasting charge. There is no need to change the batteries - this eraser includes a USB charger which can be used to recharge the battery.
Charge lasts for quite some time, thin erasers do wear down quick. Product is great, ordered anotheer one for my family to use Mel (Stockport, United Kingdom) on 6 Feb 2021
