1 The pads must be secured to the sides of the hole or the mice will eventually pull them out. 2  Large holes will need to be repaired. 3  After a couple of days, look for evidence of continuing mouse activity. 4  If there is any, check the holes that you sealed, and look for more holes.
A better measure for a pen's ink economy- and this is what they use in product testing- is writing distance. A dry ink ballpoint pen typically writes in the kilometer range- it can draw a continuous line of about 1-3km. For example, Papermate has a economy disposable pen line called Kilometrico. Bic pens fall into this category. A roller ball pen has a typical writing distance about 5-10 times less than that. Typically, 400-700m. A fountain pen has even poorer ink economy. My best guess is in the 100m-200m range, based on how often I refill my fountain pen vs replacing a roller ball.
Most authors are less frenetic. Jack London wrote between 1,000 and 1,500 words each day. Stephen King writes 2,000 words a day, and only under dire circumstances do I allow myself to shut down before I get my 2,000 words. He finishes a 180,000-word novel in three months.
