Ajaton kaksiseinäinen muki

My coffee stayed hot for a solid hour while I answered emails, which never happens with my old ceramic mug. The double-walled design keeps the outside cool too, so no more burnt fingers carrying it from the kitchen.

The double-walled design actually works, my coffee was still warm after sitting at my desk through a two-hour meeting. It's a bit heavier than my old ceramic mug but that's part of why it feels solid in the hand.

The mug keeps my coffee hot for way longer than my old ceramic one, and the sleek exterior never gets too warm to hold. It's become my daily desk companion, and the clarity of the glass makes the drink look almost too pretty to sip.
