First, more effective. After making the mouse pad, you won't let others throw it into the garbage can like other business cards and advertising leaflets, so that every part of your investment will be put into practice.
Second, the price is cheap. The effect of TV advertisement is good, but the cost is high. Newspaper advertisement is less vivid and intuitive than mouse pad. Printed publicity materials will be thrown away at random, and mouse pad can be used many times. After using this method, the threshold of advertising mouse pad is greatly reduced, and small enterprises or individual households can also have their own mouse pad, instead of being patented by large enterprises and tourist attractions.
Thirdly, there is a large amount of browsing. Generally, only one person can see a business card, and the mouse pad will let him see more relatives and friends. Increase business opportunities. Advertising is a long-term effect, long-term friends will become unfamiliar and gradually forgotten.
