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.
A good general rule is a standard letter-size sheet with 1â margins all around using a typical font such as Times New Roman at 12pt type will hold about 500 words. And not surprisingly, a half-page of text in the same scenario would be about 250 words. This is a good starting place to give you an idea of what 500 words look like on a page. But really, the last time I typed something that looked like this was back in my college days (yes, way back then).
