Thank you for viewing. I've used this several times when traveling. There is some discoloration due to age. I have wiped both the inside and outside with a disinfectant wipe. Here are some approximate measurements for reference: Bottom width: Approximately 20cm Top width: Approximately 18cm Gusset: Approximately 6cm It's still sturdy, and I'm offering it for sale to anyone who likes Cath Kidston and doesn't mind the above-mentioned points. Thank you.
