Sip on the bright side with this beautiful Rainbow Glow Double Walled Nordic Mug™! Made of double-walled borosilicate glass to help keep your tea warm (or cold) for longer, this 475 ml (16 oz) mug will put a smile on your face as sure as the sun will shine.
I wasn't sure about the rainbow finish at first, but it catches the light beautifully and the 475 ml size is perfect for my morning tea without needing a refill.
The double-walled glass actually works—my tea stayed properly hot for almost an hour instead of going lukewarm in twenty minutes. It's also lighter than I expected for a 16 oz mug, and watching the rainbow tint shift in the light is a nice little bonus every morning.
The double-walled glass really does keep my coffee hot longer than my old ceramic mug, and watching the rainbow sheen catch the light is a nice little bonus. Only gripe is it's hand wash only, which is a bit of a pain on busy mornings.
