CLEARANCE PRICED! 37x45x15mm butterfly raku bottle. The raku process combines fire and smoke to bring out the beautiful copper tones in the blue green glaze. These raku bottles are glazed on the inside also, making them watertight to hold essential oils, tears or good wishes. Each bottle comes with a cork top and is uniquely different. Pair with silk or leather cord, or make your own colorful beaded holder.
