Professional Overthinker mug. Back Reads: Sorry for Being Anxious Earlier, I had no idea everything would be fine. Great mantra for today's times! This is a handmade ceramic mug created in our New Jersey studio. This is a stoneware mug measuring 4 x 4. Interior is yellow. Kiln fired, lead free glazes. Holds 16 oz. Dishwasher and microwave safe. Great gift for a co worker or friend who tends to overthink things and a reminder not to sweat the small stuff.
