Hay Fever Hat
This hat makes it quick and convenient to blow your nose due to the ease of access and close proximity to the nostrils. It is the perfect solution for situations where you do not have fast access to tissues or you do not want to leave your location, such as a movie theater or business meeting. One obvious bonus that it did not seem to mentioned on any other sources is that not only is it good for a runny nose, but you can be sure there will be toilet paper when you use a public restroom. Just be sure to be careful about portioning out the toilet paper for both your nose and your rear end. You wouldn’t want to use to much for one and not have enough for the other. Also, it is recommended to keep an umbrella with you in case it rains so you do not end up with a soggy mess all over your head.

Butter Stick Type
Lip stick, chap stick, glue stick, now there's a butter stick? It is unconfirmed who invented this or when it was invented, but whoever invented this - I think it's a genius idea, because it's convenient unlike a regular stick of butter you just pull out of a box unless you're baking.
