It's time to get your hands on some custom mugs. They're so much more than just a mug. They're the perfect item to hold hot beverages, cold beverages, anything you want really. I know that sounds like I'm listing out the obvious things that mugs should be used for, but it's true! A mug should be both functional and stylish.
Functional it's great for when you've got research on hand and when you might need a reference of what a mug says. Then the last function of a mug is elegant. No joke, lovely gentlemen, elegant mugs are meant for wedding and engagement photos. Look at how geeky Danny Secret is holding his lovely black and white wedding mug. Does he look like he's holding a turd in that mug? I definitely don't. I'm pretty sure this is an engagement plate for some hot lady on the other side of the world, so I think the pretty designer being ignored may have something to do with it though. 

Custom mugs aren't just for holding hot beverages. You should always keep your mugs around, because no matter what business you're in, it's good business to have a good collection of mugs. My wife will literally take my wine-sipping mug with me on vacation just so I don't forget I can be stylish. Mugs are great because they're a conversation starter, they carry some memories, and they could be the perfect conversation piece to add to your business card portfolio (just make sure to save the card print image, Benjamin, for all your future business cards).
If you already have a few, or you have a lot of mugs you want to get rid of, you don't have to buy a whole new set. Instead, you can simply store some of your previous mugs in their original cardboard boxes in your bag. Why not just keep them in your bag? You'll be able to check them out at any time. I often carry several mugs in a plastic baggie on my person just in case I remember something. If you have a pile of mugs at home, you can easily donate them to your local Good Stuff Stocking Depot.
