The inner stopper on the cap actually works—I tipped it over on my desk and nothing leaked out. Mixed a custom olive drab for a tank model and the 80ml gave me plenty left over for touch-ups later.
The 80ml size is perfect for batch-mixing a whole session's worth of color without stopping to refill. The inner stopper in the cap keeps things from dripping when I shake it up, which I didn't expect to appreciate this much.
Mixing custom shades goes so much faster now that I can prep an 80ml batch and just shake it. The lid seals tight enough that I don't worry about leaks in my paint box.
