For purse vodka transporting purposes or pregaming-on-the-subway purposes, be sure to use plastic cups. They are not only the best type of vodka carriers, but they're also easy to rinse, store in your purse, & re-use later. Starbucks cups are ideal because they have lids. Cardboard cups get soggy & leak, and styro cups crumble when you put them back in your purse.
So, there you have it. You're welcome.
