Outstanding eraser. By FAR THE BEST if you write many involved equations, work
with matrices, draw graphs or do other detailed work. This is a SPOT earaser,
meant to earse just one character or two in a long equation without earaing the
rest, or earse a tiny blemish close to a line on the graph. It has clearly made
erasing screens obsolete.
Don't expect to use this for erasing a whole paragraph, or a sentence. You will
use it up it no time. SPOT erasing only. PERFECT for chemistry, mathematics or
