Contigo Autoseal Travel Mug – Five years ago, I had one of the most disastrous commutes of my life. I had put a travel mug into my Kate Spade bag and trusted that it would stay closed — you probably can see where this is going. After getting off the subway, I checked my bag and was horrified to see that coffee was just openly sloshing around the bottom of my purse, staining it forever. I’ve blocked the clean-up from my memory.
