Hearth Double Wall 6oz (175ml) Glass - Set of 2

I got mixed up between microwave safe vs dishwasher safe. They definitely aren’t safe in the latter as the plug blew and I now have condensation and free water in a mug. I was surprised to hear from the manufacturer that I should definitely not put them in a dishwasher but also avoid fully submerging the mug while hand washing as it might result in losing the plug. When I handwash drinkware I always fully submerge when washing with a cloth and then give them a hot fresh water rinse both inside and out. I love the look and being able to evaluate my level of crema but don’t find the insulation to be that outstanding and would rather preheat ceramic with hot water before I pull a shot. They are less delicate.

Beautiful piece and is amazing how well it retains the temp, though one unfortunately has a flaw in the handle.

Perfect for my morning corretto.

Really like the looks of these cups, nice shape and the colors are sharp. We have the smoke and the amber and both look good. Thermal performance is a good as expected, they keep drinks warm adequate to the volume. They cycle through the dishwasher without a hitch. Advertised as shatter resistant, but a drop from ~2' was catastrophic. My clumsiness so not a deal breaker.
