A clear acrylic block, about 6 by 4.5 inches, laid out as the periodic table with tiny real samples of 83 elements set inside, each in its own labeled square.
It sits on a desk or shelf and invites people to pick it up and look closely. For a chemistry fan, a science teacher or a student, it turns the chart on the classroom wall into something real.
It is not all 118 elements - radioactive and short-lived ones can't be included, samples are tiny, and some are shown as stable compounds or stand-ins rather than the pure element.
Skip for a chemist who would expect pure, lab-grade samples of every element.
