These are perfect for iced coffee! I would agree with others that they seem small but after I started using them I thought they were just right.

These are a tiny bit smaller in person than they may appear online, but they do technically hold exactly the amount of ml that are listed on the product page, no more no less. They are clean, clear, and quite nice. I dropped one against a quartz countertop by accident and it didn't break or even leave a mark. Very hardy

Haven't tested this item for its heatproof qualities as it's still summertime but I must say, my ice lattes are much more enjoyable in the Hario Heatproof Tumbler 420ml than any other cup/mug/tumbler. Clean, simple, and high-quality just as you would expect from any Hario product made in Japan. Highly recommended!

So pleased to discover 8oz. Was looking for an alternative to global etailer based in Seattle (with its horrible website and algorithmic service-bots). My 8oz order arrived quickly and was very well packed. Real plus is that 8oz uses Shopfiy which just speeds things along. I ordered a VCG-15 Hario 450ml glass. It rates a 10/10. Also great price on Kalita Wave 185 bulk filters. Cheers from Oak Bay, BC on the southeastern tip of Vancouver Island.
