Caffeine. Now Available in Bling.

Your favorite molecule shouldn't be relegated to casual Fridays. Bring it with you every day with a sterling silver incarnation. Designed by a wayward Ph.D. post-grad in molecular biophysics, this sterling silver caffeine molecule pendant is about 1.5 inches wide. It hangs from a sterling silver snake chain that can be adjusted for length between 16 and 18 inches.

Each necklace is packaged in a recycled gift box and includes an informational tag about caffeine. We know you're already in the know about caffeine, but if this is a gift or something that tag could come in handy. Or you could carry it with you for easier explanations when folks ask you what your necklace is all about.
