These are two erasers of the close-ups of eyes of imaginary animals that never existed, called Phabrisaurs. These erasers do a very good job of erasing pencil mistakes, which is why people will want to keep coming back to buy them over and over again.
These erasers are disposable, which means that they will each need to be replaced after a few days of use.
These erasers each have the following dimensions: length of 0.9 inches, width of 0.7 inches, and height of 0.5 inches. They each weigh 0.01 ounces.
