Lung Grapes
You’ve got a pair of lungs, so why not mirror that by having a pair of alveolus cufflinks on your sleeves? These grape-like sacs play a crucial role in gas exchange – allowing oxygen to diffuse into your bloodstream and CO2 to leave. Purchase these cufflinks for yourself or for a friend. They also make a great gift for your favorite pulmonologist, marathon runner, endurance athlete, or starry-eyed pre-med student.
