Spare glass carafes for Penguin machine owners. If you have a Fountain Jet, Edition 1 or Design machine you can add a 'touch of glass' by carbonating your drinks in the PET bottles (BPA-free!) that came with your soda maker, then transferring your carbonated drink to these elegantly crafted glass carafes for serving and storage. Each bottle holds 620ml and comes with a fizz-preserving closure. Dishwasher-safe.
