I got this one for my wife for that exact thing. I haven't heard of it leaking at all and the locking mechanism seems very solid. It's also pretty slim and fits in her purse and is dishwasher safe.

It's been a fun game to watch as a Jays fan (Go Jays, indeed!)

Hey it's that giant thing that has my chocolate chip cookie recipe!

I’ll soon be available for game design, creative direction, and consultancy opportunities while I develop my own projects. I’m also open to paid speaking engagements if you know of any!

If you’d be willing to share/repost this, or just send a kind word, I’d truly appreciate it. Thank you! ♥

Neat! Your picture turned out much better but I took almost the same shot without knowing what it was until I saw your post

I don't remember where you are located but if you are in Toronto I have some contacts that could help you with this

That's the one I always think of whenever these things come up 🙂
