Smaller, very affordable Trinitite samples. These thumbnail Trinitite samples typically measure about 1/2" across and come mounted on heavy-stock, high-gloss Kodak photo paper with a thick cardboard backing. The image printed is an atomic detonation with an informative description of Trinitite and its origin. Overall size is 5" x 7". A certificate of authenticity is included. The small pad that the Trinitite is mounted on glows in the dark making the sample look quite impressive in dim light. All Trinitite is slightly radioactive, but perfectly safe to handle.
