I love caffeine. Chances are, you do, too.
Found in a dizzying array of our favorite beverages, caffeine causes decreased activity of the relaxing neurotransmitter adenosine and a surge of norepinephrine, keeping us awake and alert. The buzz feeling comes from increased dopamine. Caffeine may also increase serotonin, the neurotransmitter that makes us feel pleasantly happy.
These solid sterling silver cufflinks is based on the caffeine molecule. They are each about about .75 inches wide. Each pair is packaged in a recycled gift box and includes an informational tag about caffeine. A wonderful gift for the caffeine lover in your life!
