Mine are the 8.5 ounce size. They’re 4 dollars each. That may be a little high, though, if you’re buying for a crowd. We only have 4 and it’s a tax write off for me, so I was able to justify the expense. We’ve had them for ages, though, and as long as we take off the little red rubber washer, we can clean them in the dishwasher, so I don’t regret buying them.
