Always maintain a supply of water. Beginner preparers should start with a food supply of no more than 30 days. Needless to say, you should always have a first aid kit handy. I'm not trying to do big things, but a titanium cup has its place in a kit, but that depends.
First of all, it's a mug and it's a metal mug. The reason it's a metal mug is because you can use it on fire to purify water. But metal does not necessarily have to be titanium, and for less than a quarter of the price, a steel cup will do. Which is not to say that you shouldn't have a titanium cup.
First you have to know who you are in the preparation and why you think titanium would be more beneficial to the way you are going to advance than steel, then you will know why you want the titanium cup instead of the steel one. But to come and recommend a titanium cup to someone who still doesn't know why he needs it, well, that's not that useful. Under no circumstances do you need to have the titanium cup. If you want to have one, and you can afford it, of course.
But at home, all the things you normally drink from will continue to work. If you're getting into it, a steel cup is much cheaper. It sure weighs a little more, costs much less, and remember the premise, are you trying to prepare in your first month? Right? So save money on the titanium cup for now. Also, don't use tampons as the only water filter.
There is an urban legend going around that the tampon can be used as the only filter for water. The tampon will filter out dirt but will not leak anything else. If you want a terminal box of brown drizzles, step aside with a tampon. My question is what is the titanium cup for? Is it like the old Sierra cups? How do I start preparing? Effective preparedness starts with a personal risk assessment to determine the threats you face and where you need to focus most of your time and resources.
Once you know what you're preparing for, it's a good idea to focus on the basics of water, food, housing, fuel, and sanitation. Honey is known to be one of the only foods that can last forever. This is largely due to the fact that it is made from sugar, which makes it difficult for bacteria or microorganisms to affect honey.
