What’s this?

I have 7 different floaty pens in my purse right now. I got them by attending conferences at different museums or they are left over from old exhibits we used to have. I feel weird about it because a.) what if they leak all over my purse? (Although, I’ve never actually heard of or seen a leaky floaty pen.) and b.) aren’t they supposed to be collectible? Hmm….but it’s so cool to whip out a floaty pen every time you have to write a check.
