The other day I met a friend for an outting at the Denver Museum of Nature and Science. As I was packing up our lunches, I decided to bust out the Tiffin. Our Tiffin is large, so it's more like a picnic lunch size. Rather than pack 3 separate bentos, I just packed one Tiffin! It has three stacking trays that lock into one another. I used the top as a plate for one of my daughters. One tray contains our sandwiches or meat/cheese wraps, Whole Foods 365 cheese puffs, and some fresh strawberries with decorative picks. Easy and waste free.
Very convenient and fun!
If you like the ease of a Tiffin, I recently saw a personal size one for very cheap at Cost Plus World Market. There are also many websites, just search Tiffin.
