Akro Agate did not make Cat’s-Eyes. However, they did produce a beautiful clear-based marble with multicolored opaque filaments, known as the Sparkler. Akro Sparkers were made with very clear smooth-surfaced glass, which helps to differentiate them from German Sparklers which sometimes had a light to heavy amount of surface "orange peel" texture. Akro Sparlers are thought to have had at least five colors, which is commonly used to differentiate them from the Clear Sunbursts made by Master. Some of the Akro Sparklers included Oxblood.
