These tumblers vary wildly and are each a pleasure to gaze at. The decoration can range the full spectrum of opaque and transparent colours, earth tones, jewel tones, primary colour blocks, sparkly bits and mood ring areas, dots, lines and squiggles. Made by rolling random handfuls of colourful bits onto molten glass, they are fused and smoothed in the process and then iridized once the cup shape is formed. Each cup will be entirely unique from the ones pictured and we can't guarantee that certain colours will or won't be present. It'll just be a pleasant surprise.
