These are the kids' version and are great for kids 5 and over. They come in green, orange, pink and blue. The "ears" make the lids easy for small fingers to remove.
These two below are the more "grown up" ones. Just because their colors are more subdued, and they don't have "ears". This series is called "Too cool for ears" and is suggested for adults and kids over 9 years old. Whatever. I'd do the ears ones--they're cuter! Both styles come with 275 stickers to use to personalize your goodbyn. The colors for the earless ones are white, charcoal, plum, and navy.
