I bought both the Brüu amber latte and iced coffee glasses and they are absolutely Brüutiful. The way the light hits that amber tint makes my coffee look like liquid gold. Borosilicate glass?Turns out, it’s some kind of fancy glass NASA uses for space coffee. These bad boys are sleek and basically indestructible. If you’re ready to level up your latte game, grab a couple Brüu cups and take a ride through the Brüuniverse where every sip is out of this world.
