1oz (50ml) jars. Jars measure 1″ tall by 2.25″ diameter. Festival glitter is a mixture of chunky, holographic glitters and gel. It can be applied to hair and skin, but one should avoid putting it too close to the eyes or on the eyelids or putting on very small children who can rub it into their eyes. Filbert brushes or silicone applicators work great for applying Glitter Glaze! For best results and consistency, store at room temperature.
