New for 2022 comes our “version 3.0” case for the 10mm cubes which now includes ampule cutouts for those elements which are not stable in air. While we have been selling 10mm reactive metal cubes inside glass ampules for years these have never had a ‘home’ - until now! Each hole is sized 18mm and will fit the new, flat-bottomed cubes-in-ampules that are now standard. The squares are sized 14mm and fit the metal cubes with the protective boxes they ship in so they are never directly exposed. The lettering now includes all elements up to oganesson. Measures 15.5”x8.5”

Please note that the current batch of these displays do not have cutouts for Li, Na, K, Rb & Cs.
