Fast forward. My 19 year old ordered me one off the internet and gave it to me as a Mother's Day gift. I got it on a Sunday and took it to work with me on Monday morning. While at a staff meeting my Director (sitting to my right) kept looking at my coffee mug instead of concentrating on the meeting. Finally he reached over and started to touch the brown 'paper sleeve' around it. He interrupted the meeting to ask me about my coffee mug.
My "paper" coffee travel cup was actually an Eco Cup - it looks like a paper mug you get in the drive thru and toss into the trash/landfill but it's not! One of my coworkers makes comments about any of us who bring a paper or Styrofoam cup into work so I was hoping she was paying attention when I explained it only LOOKED like a paper coffee cup - it was really ceramic and environment friendly!
My version is single-walled (non-thermal) porcelain cup with silicone lid and sleeve. Holds approximately 16oz with a brown sleeve. It's microwave and dishwasher safe. But a quick check of Amazon this morning showed me there were a number of choices available. Check it out if you're looking for a fun Father's Day gift or even a gift for the coffee-loving graduate for the long study-nights at college!
