IT’S THE LITTLE THINGS THAT MATTER. The creators of the “Anatomy in a Jar” series promise nothing less than a vacuum-sealed life-sized molar of exceptional detail with this offering. If your gift is seeking to satisfy a dentist with an eye for detail, this may be the perfect, or nearly perfect, option. Tiny dark flecks on the tooth’s surface simulate the real deal. Find it on etsy.com for $95.
