Set of 2 Double Trouble Cups in Pink. Double Trouble Cups are a tribute to the fun which comes from a best friend or ‘partner in crime’ (which is why they come as a set of two). It’s basically a ‘cheers’ to those essential people in our lives. Made from heat resistant borosilicate glass, designed with a durable double wall construction ensuring optimal insulation for your tea or coffee for a longer period of time. Due to the nature of the double wall glass, we recommend hand washing for longevity of use. Cup specifications: 8.5cm diameter x 7.5cm high, approx. 250ml capacity.
